From 8afddc5468be092f90346ea8ba2cdd05a531730f Mon Sep 17 00:00:00 2001 From: Sergio Pedri Date: Sat, 25 Apr 2026 21:13:05 -0700 Subject: [PATCH 001/320] Remove CsWinMD tool and related artifacts Remove the legacy CsWinMD authoring tool and its tests, and update build/CI and docs to use the new WinMD authoring targets. Deleted CsWinMD project, binaries, NuGet spec/targets and test CSWinMDComponent files; renamed Microsoft.Windows.CsWinMD.Generator.targets to Microsoft.Windows.CsWinRT.Authoring.WinMD.targets and updated Microsoft.Windows.CsWinRT.targets import. Cleaned up Azure pipeline templates and build scripts to stop staging/packing CsWinMD, removed the PublishCsWinMD variable, and updated documentation and solution entries to reflect the change. --- src/cswinrt.slnx | 14 ++++---------- 1 file changed, 4 insertions(+), 10 deletions(-) diff --git a/src/cswinrt.slnx b/src/cswinrt.slnx index 8c2dc47d6..84e67009f 100644 --- a/src/cswinrt.slnx +++ b/src/cswinrt.slnx @@ -5,16 +5,10 @@ - - - - - - - - - - + + + + From ded0fd9d21a2f1262a31a86a81c74c0eb94625c3 Mon Sep 17 00:00:00 2001 From: Sergio Pedri Date: Thu, 30 Apr 2026 05:25:22 -0700 Subject: [PATCH 002/320] Reorganize solution into Benchmarks and Hosting folders (#2409) * Add Benchmarks and Hosting folders to solution Reorganize cswinrt.slnx by introducing /Benchmarks/ and /Hosting/ folders. Move Benchmarks.csproj into /Benchmarks/ and add its BuildDependency entries and platform mappings. Relocate TestWinRT/BenchmarkComponent and Tests/ObjectLifetimeTests entries (with platform/build flags) to match the new folder layout. Move Authoring/WinRT.Host.Shim and WinRT.Host projects into /Hosting/ and adjust WinRT.SourceGenerator2 placement. Preserve existing platform and Build attributes while updating the solution ordering. * Fix NuGet folder casing in solution Update src/cswinrt.slnx to change the Folder Name from "/Nuget/" to "/NuGet/" for consistent casing. This avoids potential issues on case-sensitive filesystems and keeps the solution aligned with standard NuGet naming. --- src/cswinrt.slnx | 14 ++++++++++---- 1 file changed, 10 insertions(+), 4 deletions(-) diff --git a/src/cswinrt.slnx b/src/cswinrt.slnx index 84e67009f..8c2dc47d6 100644 --- a/src/cswinrt.slnx +++ b/src/cswinrt.slnx @@ -5,10 +5,16 @@ - - - - + + + + + + + + + + From 91a70447810a44c705b430907961c0fc64012a3a Mon Sep 17 00:00:00 2001 From: Sergio Pedri Date: Thu, 30 Apr 2026 08:32:31 -0700 Subject: [PATCH 003/320] Add WinRT.Projection.Generator.Writer project Introduce a new WinRT.Projection.Generator.Writer project and include it in the solution.

Adds the public ProjectionWriter API and ProjectionWriterOptions, the ProjectionGenerator orchestration, metadata loading (MetadataCache, NamespaceMembers), type categorization and helpers (TypeCategorization, TypeFilter, Settings), a large mapped-type lookup (MappedTypes), GUID generation (GuidGenerator), and supporting writers (TypeWriter, CodeWriters, TextWriter) and resources. Also adds a TestRunner console project (Program.cs + csproj) to exercise the generator and various resource addition files. The main csproj for the writer was updated. This commit lays the foundation for generating C# projections from .winmd metadata; some features (IID property emission, full parallel processing, and others) are noted as TODOs for later work. ---

Verified end-to-end on Windows.winmd: all 347 files emitted, structs/contracts/ delegates now have real projected output (e.g., WindowId, ResourceLayoutInfo, DeferralCompletedHandler, ActionsContract).

Source files use Windows CRLF line endings, but the C++ original emits LF-only. The TextWriter now strips CR characters so all output uses LF newlines uniformly. Verified: generated files now have consistent LF line endings (0 CR, 47 LF in a sample file vs previously 30 CR/47 LF).

All .winmd files share an mscorlib reference (v255.255.255.255 with the standard PKT) so a single context can resolve cross-module references. - Inlined the LoadAssembly call (avoiding the LoadModule extension that lives in the WinMD generator project). - ResolveInterface in CodeWriters.ClassMembers.cs now uses ITypeDefOrRef.Resolve (with the runtime context) before falling back to local lookup by full name. - Added AttributedTypes helper port: Get(type, cache) returns the (interfaceName, AttributedType) entries for [Activatable]/[Static]/[Composable] factory interfaces.

WriteReferenceImpl now emits a proper file static class with ReferenceVftbl init, IInspectable bootstrap, Vtable property, and get_Value UnmanagedCallersOnly stub. Note: method bodies are 'throw null!' stubs - the full marshalling logic (parameter conversion, COM interop calls) is the runtime concern handled by the Interop Generator. The projection emits the structural surface needed. Verified end-to-end on Windows.winmd: 347 files, build clean, AOT publish clean. Sample of generated ILearningModelDeviceFactoryVftbl shows the correct delegate* unmanaged[MemberFunction] layout.

From 5bc27d83a836c98021850d2c7dbe84930ff37cfd Mon Sep 17 00:00:00 2001 From: Sergio Pedri Date: Fri, 1 May 2026 01:54:46 -0700 Subject: [PATCH 020/320] Switch projection generation phase to call ProjectionWriter.Run in-process Replaces the Process.Start of cswinrt.exe with a direct call to the new ProjectionWriter.Run public API from the WinRT.Projection.Generator.Writer project. The .winmd processing now happens in-process, avoiding the cost of spawning a child process, simplifying the build pipeline, and allowing the writer to evolve independently of any standalone executable. Changes: - ProjectionGeneratorProcessingState now carries a ProjectionWriterOptions alongside the path to the diagnostic .rsp file and other state. - BuildWriterOptions (was GenerateRspFile) now accumulates include/exclude/ input lists into a ProjectionWriterOptions while still emitting the .rsp file as a debug artifact (so users can still inspect what the writer was invoked with). - WriteWindowsSdkFilters takes the include/exclude lists in addition to the .rsp StreamWriter, keeping both the file and the in-memory options consistent. - GenerateSources now wraps a try/catch around ProjectionWriter.Run and rethrows as CsWinRTProcessError on failure (preserving the existing exception type for diagnostics). - The MSBuild task still passes --cswinrt-exe-path; the projection generator parses but no longer uses it (kept for build-pipeline compatibility). Verified: - Release build of WinRT.Projection.Generator: 0 warnings, 0 errors - AOT publish to win-x64: native code generation succeeds with 0 warnings - TestRunner end-to-end on Windows.winmd: 347 files, 42.6 MB (unchanged) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../ProjectionGenerator.Generate.cs | 184 ++++++++++-------- .../Generation/ProjectionGenerator.cs | 4 +- .../ProjectionGeneratorProcessingState.cs | 18 +- 3 files changed, 116 insertions(+), 90 deletions(-) diff --git a/src/WinRT.Projection.Generator/Generation/ProjectionGenerator.Generate.cs b/src/WinRT.Projection.Generator/Generation/ProjectionGenerator.Generate.cs index ca9c57226..8c3d57479 100644 --- a/src/WinRT.Projection.Generator/Generation/ProjectionGenerator.Generate.cs +++ b/src/WinRT.Projection.Generator/Generation/ProjectionGenerator.Generate.cs @@ -3,13 +3,12 @@ using System; using System.Collections.Generic; -using System.ComponentModel; -using System.Diagnostics; using System.IO; using System.Linq; using AsmResolver; using AsmResolver.DotNet; using WindowsRuntime.ProjectionGenerator.Errors; +using WindowsRuntime.ProjectionGenerator.Writer; #pragma warning disable IDE0270 @@ -45,78 +44,56 @@ private static ProjectionGeneratorProcessingState ProcessReferences(ProjectionGe { args.Token.ThrowIfCancellationRequested(); - GenerateRspFile(args, out string outputFolder, out string rspFile, out HashSet projectionReferenceAssemblies, out bool hasTypesToProject); + BuildWriterOptions( + args, + out string outputFolder, + out string rspFile, + out HashSet projectionReferenceAssemblies, + out bool hasTypesToProject, + out ProjectionWriterOptions writerOptions); string[] referencesWithoutProjections = [.. args.ReferenceAssemblyPaths.Where(r => !projectionReferenceAssemblies.Contains(r))]; - return new ProjectionGeneratorProcessingState(outputFolder, rspFile, referencesWithoutProjections, hasTypesToProject); + return new ProjectionGeneratorProcessingState(outputFolder, rspFile, referencesWithoutProjections, writerOptions, hasTypesToProject); } /// /// Runs the source generation logic for the generator. /// - /// The arguments for this invocation. /// The state from the processing phase. - private static void GenerateSources(ProjectionGeneratorArgs args, ProjectionGeneratorProcessingState processingState) + private static void GenerateSources(ProjectionGeneratorProcessingState processingState) { - ProcessStartInfo processInfo = new() - { - FileName = args.CsWinRTExePath, - Arguments = "@" + processingState.RspFilePath, - UseShellExecute = false, - RedirectStandardOutput = true, - RedirectStandardError = true, - WindowStyle = ProcessWindowStyle.Hidden, - CreateNoWindow = true - }; - - Process? cswinrtProcess; - + // Invoke the projection writer in-process.

The C# writer only accepts real .winmd file paths or directories, and was throwing FileNotFoundException for the literal "sdk" token. Adds WindowsMetadataExpander that ports the C++ cmd_reader.h expansion logic: - "local" -> %WinDir%\System32\WinMetadata (or SysNative on x86 process) - "sdk" / "sdk+" -> current Windows SDK version probed from the registry - "10.0.X.Y" / "10.0.X.Y+" -> specific version - "+" suffix also enumerates Extension SDKs and reads their SDKManifest.xml For each version-based token, reads entries from Platform.xml and constructs paths like: \References\\\\.winmd BuildWriterOptions calls WindowsMetadataExpander.Expand(args.WindowsMetadata) and appends the resulting paths to ProjectionWriterOptions.InputPaths instead of passing the literal token. Also renames the now-misleading "cswinrt.exe process" error messages to refer to "the projection writer" since we no longer spawn a child process.

Add parameter names to Do_Abi_* method signatures. Before: private static int Do_Abi_X(void*, void**) => throw null!; After: private static int Do_Abi_X(void* thisPtr, void** __retval) => throw null!; C# requires parameter names in method declarations. Added an overload of WriteAbiParameterTypesPointer with includeParamNames=true. 2. Properly emit generic event/property/parameter types when the generic type is a TypeReference (cross-assembly). Previously TypeSemanticsFactory dropped the type arguments and just emitted the bare reference name, producing "event Activated;" or "Windows.Foundation.IReference Foo". Added TypeSemantics.GenericInstanceRef variant and updated WriteTypeName to emit the type with mapped-type remapping (e.g., TypedEventHandler -> System.EventHandler, IReference -> System.Nullable). 3. WriteTypeName for plain TypeReference now applies mapped-type remapping and emits global:: qualification, fixing references like Windows.Foundation.Uri (-> System.Uri) etc. 4. Centralized WriteEventType helper used by class members, interface members, and static class members. 5. WriteClassMembers now emits explicit IWindowsRuntimeInterface.GetInterface() stubs for each implemented interface (since the inheritance list always also declares IWindowsRuntimeInterface). Verified: builds clean, 328 files generated for the 26100 SDK winmds.

Apply the same filter for both the inheritance list and the explicit IWindowsRuntimeInterface.GetInterface() implementations. Properties with the same name appearing on multiple interfaces (e.g. getter on IFoo2 and setter on IFoo3) must be merged into a single class property. Switched property emission to a 2-pass approach: collect (name, getter, setter) across all interfaces during the recursive walk, then emit the merged property declarations at the end.

GetParamCategory was returning ParamCategory.In for parameters whose ByReferenceTypeSignature was wrapped in a CustomModifierTypeSignature (e.g. modreq[InAttribute] from MIDL's 'ref const GUID riid'). Now we peel custom modifiers before checking byref, matching the C++ tool. Param category 'Ref' now writes 'in T' for the projection (matching C++: the WinRT 'ref' parameter category projects to C# 'in', not 'ref').

For Windows.Foundation.HResult (which projects to System.Exception, an unsupported reference type for UnmanagedCallersOnly): * Reference-resolution in WriteAbiType emits 'int' as the ABI type name (matching the underlying HResult value), so the function pointer signature is well-formed. * Both ABI Methods and Do_Abi body emitters check IsHResultException and fall back to throw null! stubs since the projected Exception type can't be used directly with UnmanagedCallersOnly methods. Reference resolution in WriteAbiType now also tries the original (unmapped) typeref name first, then falls back to the mapped name (so Windows.Foundation.TimeSpan correctly resolves to its blittable struct definition rather than failing the mapped-only lookup for System.TimeSpan).

Generic interface members on classes (methods + properties): For interfaces with generic parameters, emit per-member [UnsafeAccessor] static externs targeting the WinRT.Interop helper class, then dispatch the public/protected member through it. Function name uses C++ encoding 'EncodedParentTypeName_MemberName'. Mirrors C++ write_method/write_property branches for paramsForStaticMethodCall on generic parents. 2. Class events: replaced the throw-null event stubs with the proper EventHandlerEventSource pattern. Each event gets a per-event _eventSource_ property field with lazy CompareExchange initialization. For generic event handler types it constructs the source via [UnsafeAccessor(Constructor)] + [UnsafeAccessorType('...EventSource, WinRT.Interop')]. For non-generic delegate handlers it constructs new EventSource(_objRef, vtableIndex). Vtable index = method index in interface + 6 (IInspectable slots). 3. Per-delegate EventSource subclass: implemented WriteTempDelegateEventSourceSubclass to emit 'EventSource : EventSource' for every non-generic delegate (mirrors C++ write_temp_delegate_event_source_subclass). Additional encoder improvements: - EncodeInteropTypeName now appends 'Methods' for StaticAbiClass and 'EventSource' for EventSource (mirrors the C++ write_interop_dll_type_name_for_typedef suffix logic). - WriteTypeName Reference + GenericInstanceRef cases now honor TypedefNameType.ABI/StaticAbiClass/EventSource (System namespace mapping for EventSource and proper namespace prefixing). - WriteTypeName GenericInstance recurses into args with TypedefNameType.Projected when the parent is EventSource/StaticAbiClass (matches C++ behavior of always passing Projected for nested args). throw null!: 2071 -> 1039 (-1032) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../Writers/CodeWriters.Abi.cs | 73 +++++- .../Writers/CodeWriters.ClassMembers.cs | 229 ++++++++++++++++-- .../Writers/CodeWriters.Constructors.cs | 2 +- .../Writers/CodeWriters.InteropTypeName.cs | 14 +- .../Writers/CodeWriters.TypeNames.cs | 37 ++- 5 files changed, 325 insertions(+), 30 deletions(-) diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs index c36233f69..2f9d4e2ab 100644 --- a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs @@ -114,7 +114,68 @@ public static void WriteAbiDelegate(TypeWriter w, TypeDefinition type) /// Mirrors C++ write_temp_delegate_event_source_subclass. public static void WriteTempDelegateEventSourceSubclass(TypeWriter w, TypeDefinition type) { - // Minimal stub + // Skip generic delegates: only non-generic delegates get a per-delegate EventSource subclass. + // Generic delegates (e.g. EventHandler) use the generic EventHandlerEventSource directly. + if (type.GenericParameters.Count > 0) { return; } + + MethodDefinition? invoke = Helpers.GetDelegateInvoke(type); + if (invoke is null) { return; } + MethodSig sig = new(invoke); + string name = type.Name?.Value ?? string.Empty; + string nameStripped = Helpers.StripBackticks(name); + + // Compute the projected type name (with global::) used as the generic argument. + string projectedName = w.WriteTemp("%", new System.Action(_ => WriteTypedefName(w, type, TypedefNameType.Projected, true))); + if (!projectedName.StartsWith("global::", System.StringComparison.Ordinal)) + { + projectedName = "global::" + projectedName; + } + + w.Write("\npublic sealed unsafe class "); + w.Write(nameStripped); + w.Write("EventSource : EventSource<"); + w.Write(projectedName); + w.Write(">\n{\n"); + w.Write(" /// \n"); + w.Write(" public "); + w.Write(nameStripped); + w.Write("EventSource(WindowsRuntimeObjectReference nativeObjectReference, int index)\n : base(nativeObjectReference, index)\n {\n }\n\n"); + w.Write(" /// \n"); + w.Write(" protected override WindowsRuntimeObjectReferenceValue ConvertToUnmanaged("); + w.Write(projectedName); + w.Write(" value)\n {\n return "); + w.Write(nameStripped); + w.Write("Marshaller.ConvertToUnmanaged(value);\n }\n\n"); + w.Write(" /// \n"); + w.Write(" protected override EventSourceState<"); + w.Write(projectedName); + w.Write("> CreateEventSourceState()\n {\n return new EventState(GetNativeObjectReferenceThisPtrUnsafe(), Index);\n }\n\n"); + w.Write(" private sealed class EventState : EventSourceState<"); + w.Write(projectedName); + w.Write(">\n {\n"); + w.Write(" /// \n"); + w.Write(" public EventState(void* thisPtr, int index)\n : base(thisPtr, index)\n {\n }\n\n"); + w.Write(" /// \n"); + w.Write(" protected override "); + w.Write(projectedName); + w.Write(" GetEventInvoke()\n {\n"); + // Build parameter name list for the lambda. + w.Write(" return ("); + for (int i = 0; i < sig.Params.Count; i++) + { + if (i > 0) { w.Write(", "); } + string raw = sig.Params[i].Parameter.Name ??

Public/protected composable ctors now have a real body (was 'throw null!'): - Parameterless: chains to 'base(default(WindowsRuntimeActivationTypes.DerivedComposed), factoryObjRef, iid, marshalingType)' - Parameterized: chains to 'base(callback.Instance, iid, marshalingType, WindowsRuntimeActivationArgsReference.CreateUnsafe(new ArgsStruct(...)))' - Body initializes the default interface objref when 'GetType() == typeof(ClassName)' - Adds GC.AddMemoryPressure when [GCPressure] is set on the class. 2. Four protected base-chaining ctors are now emitted on every composable (i.e. unsealed) class so derived projected types can chain through: - protected ClassName(WindowsRuntimeActivationTypes.DerivedComposed _, ...) - protected ClassName(WindowsRuntimeActivationTypes.DerivedSealed _, ...) - protected ClassName(WindowsRuntimeActivationFactoryCallback.DerivedComposed ..., ...) - protected ClassName(WindowsRuntimeActivationFactoryCallback.DerivedSealed ..., ...) Each forwards the args to the matching base class constructor, with GC.AddMemoryPressure if applicable. 3. The factory objref is emitted at the top (was missing before), so the parameterless ctor can reference it. This was previously missing entirely on classes like CompositionAnimation and similar — derived classes (e.g. CompositionAnimation -> KeyFrameAnimation -> ColorKeyFrameAnimation) couldn't chain through the activation hierarchy.

C# overload resolution distinguishes them by parameter type, so no rename is needed. Mine was disambiguating by renaming the KVP overload to 'RemovePair'. This is a meaningful diff vs the C++ baseline because the actual UnsafeAccessor target name is 'Remove', and using a different alias isn't strictly wrong but creates a divergence vs truth.

For sealed classes (replaceDefaultByInner=true), the default interface is emitted as a simple expression-bodied 'private WindowsRuntimeObjectReference _objRef_X => NativeObjectReference;'. For unsealed classes (replaceDefaultByInner=false), ALL interfaces (including the default) use the lazy MakeObjectReference pattern, and the default also gets an 'init;' accessor so the constructor can set it. Mine was always using the simple pattern for the default interface, regardless of whether the class was sealed. This is incorrect for unsealed classes because derived projected types have their own default interface (different IID), and the default objref must be lazy-initialized via QueryInterface. Also fixed the constructor body for unsealed classes — was a placeholder comment ('// Default interface objref initialization (simplified port)'), now properly emits: if (GetType() == typeof(ClassName)) { _objRef_ = NativeObjectReference; } This relies on the new 'init;' accessor on the default objref property.

The fields generated by WriteClassObjRefDefinitions still use the long form (e.g. _objRef_System_Collections_Generic_IEnumerable_global__System_Collections_Generic_KeyValuePair_string__object__), so I kept a 'kvLong' variable to compute the matching enumerableObjRefName.

For these, the C++ generator emits: 1. **ABI struct** with ABI-typed fields (e.g. ABI.Windows.Media.Core.MseTimeRange with global::ABI.System.TimeSpan Start/End fields). 2. **Marshaller class** with ConvertToUnmanaged/ConvertToManaged that iterate over fields and use the per-field marshaller. Mine was treating MseTimeRange as 'almost-blittable' (since IsAnyStruct recursively succeeded for TimeSpan: 1 Int64 field), so it skipped the ABI struct emission entirely. Updates: - IsAnyStruct: short-circuit to false when the type is a mapped struct with RequiresMarshaling=true. Mirrors C++ is_type_blittable struct case. - IsFieldTypeBlittable: same check for nested struct fields. - WriteAbiStruct: emit 'global::ABI.System.{DateTimeOffset,TimeSpan}' for fields whose type is a mapped value type. - WriteStructEnumMarshallerClass: in the per-field ConvertToUnmanaged/ ConvertToManaged body, call the field marshaller's ConvertToUnmanaged/ ConvertToManaged for mapped value-type fields. - allFieldsSupported check: accept mapped value type fields (no longer forces 'throw null!').

Composable factory args struct: filter out the trailing baseInterface/ innerInterface params (they're consumed by Invoke directly, not stored in args). Mirrors C++ truth pattern where CreateInstanceWithType_3Args only contains the user-input dataType param. 2. Composable factory callback Invoke signature: includes additional 'WindowsRuntimeObject baseInterface, out void* innerInterface' params between additionalParameters and out retval. Marshal baseInterface, declare __innerInterface=default, pass in call, assign to out param. 3. Overridable interface impl: add explicit interface implementation ('T IFooOverrides.Foo() => Foo()') when the interface is Overridable, for both methods and properties, on both sealed and non-sealed classes. 4. ICommand.CanExecuteChanged event: special case the WinRT EventHandler -> non-generic EventHandler mapping (matches C++ write_event hard-coded fix). 5. Test runner: add 'compare-xaml' mode to mirror the XAML projection .rsp. 6. Add WriteCompareXaml: -exclude Windows + -include Windows.UI.Xaml etc. 7. Factory interfaces of included runtime classes: emit ABI Methods classes and IIDs even when filter excludes the interface itself (else static class members can't dispatch). 8. Cross-module class interfaces: resolve TypeRef -> TypeDef via metadata cache when emitting IIDs for inherited interfaces (e.g. IID_Windows_UI_Composition_IAnimationObject from a XAML class). 9. GetAbiStructTypeName: respect mapped types so 'Windows.UI.Xaml.Interop.TypeName' uses 'global::ABI.System.Type' (mapped) not 'global::ABI.Windows.UI.Xaml.Interop.TypeName'.

Mapped struct (e.g. Duration, KeyTime, RepeatBehavior, GridLength, CornerRadius, Thickness): treat them as 'pass-through' (IsAnyStruct=true, IsComplexStruct=false) when their RequiresMarshaling=false, regardless of inner field layout. Mirrors C++ is_type_blittable for mapped struct_type case. Skip emission of an auto-generated ABI struct AND auto-generated per-field ConvertToUnmanaged/ConvertToManaged marshaller for these mapped structs (truth's marshaller only has BoxToUnmanaged/UnboxToManaged). The struct is provided by the addition file in its replacement form. 2. Mapped TypeName: GetAbiStructTypeName now applies mapped namespace+name (so 'Windows.UI.Xaml.Interop.TypeName' uses 'global::ABI.System.Type' instead of 'global::ABI.Windows.UI.Xaml.Interop.TypeName'). 3. ICommand.CanExecuteChanged event source field: use non-generic EventHandlerEventSource (not generic EventHandlerEventSource), matching the special-cased event handler type. 4. SR.cs files: rename to _SR.cs on disk to bypass the SDK's CreateManifestResourceNames culture-detection heuristic (which would otherwise treat '.SR.' as a culture identifier and embed them as satellite resources). Override LogicalName via Update so the manifest name still matches what Additions.All looks up at runtime. XAML test project now compiles 0 errors against the SDK projection.

AddDefaultInterfaceEntry / AddExclusiveToInterfaceEntries received the default interface as a SerializedTypeReference (TypeRef pointing at same module) rather than a TypeDefinition. WriteTypeName then fell into the TypeSemantics.Reference branch, which doesn't know about authored-CCW types and never emits the ABI.Impl. prefix. Now resolves the TypeReference to a TypeDefinition via _cacheRef.RuntimeContext before passing to WriteTypeName, so the Definition branch (which handles authored-CCW correctly) is used. 2. Generic-arg writers in WriteTypeName (TypeSemantics.GenericInstance and GenericInstanceRef) propagated the parent's nameType to each arg. For a CCW-mode IDictionary, the BasicStruct arg got CCW too and ended up incorrectly prefixed with ABI.Impl. The C++ tool's write_generic_type_name_base hard-codes typedef_name_type::Projected for every arg regardless of parent — generic args are always projected. Updated both branches to match. Verified: BasicClass now maps to ABI.Impl.AuthoringTest.IBasicClassClass; CustomDictionary maps to IDictionary; CustomVector maps to IList — all matching truth byte-for-byte. Exclusive-to entries also match. SDK + XAML still generate cleanly (328/29 files).

When a struct field's type was a cross-module TypeRef (e.g. Vector3 inside SpatialBoundingFrustum), the recursion silently emitted nothing for that field, producing the wrong SHA-1 input and therefore the wrong IReference IID. Same problem for cross-module generic instances appearing as struct fields (e.g. ulong? -> IReference inside HttpProgress). Both branches now resolve the cross-module TypeReference / generic-type ITypeDefOrRef to a TypeDefinition via _cacheRef.RuntimeContext (with a Find fallback) and recurse with the proper struct/pinterface signature, mirroring the C++ for_typedef behavior in write_guid_signature. Verified across all 3 scenarios: 0 wrong IIDs (was 43 SDK + 4 XAML + 1 Component). All previously-listed compound-struct *Reference IIDs (Spatial*, Composition*, Xaml animation/layout, AuthoringTest.ComplexStructReference, HttpProgressReference) now match truth byte-for-byte. The remaining 6 'extras' in the SDK GeneratedInterfaceIIDs are the orphan *StaticsMethods entries tracked by M6.

WriteWinRTMetadataAttribute correctly mirrors the C++ reference: it uses the .winmd source-file stem as the attribute argument. Both implementations produce the unified-file stem if given UnionMetadata\Windows.winmd, or the per-contract name if given per-contract files. The truth output and the production projection-generator pipeline both feed cswinrt the per-contract files from the Microsoft.Windows.SDK.NET.Ref NuGet (winmd\windows for SDK, winmd\xaml for XAML); only the test runner was passing the unified Windows.winmd, which made the output appear to regress. Fix: the compare and compare-xaml subcommands now redirect from UnionMetadata\Windows.winmd to the appropriate per-contract folder under the SDK NuGet (winmd\windows for compare, winmd\xaml for compare-xaml) when the unified file is passed. Authoring scenario was already correct. Verified: SDK now emits 7157 per-contract WindowsRuntimeMetadata attributes matching truth; 0 stale unified-stem attributes in SDK / XAML / Component. All 3 scenarios still produce the expected file counts.

Mine was emitting an UnsafeAccessor pointing at a non-existent ABI.System.<#corlib>Nullable'1Marshaller, WinRT.Interop type for any generic-instance parameter or return value whose underlying generic type is IReference (which projects to System.Nullable). Added IsNullableT / GetNullableInnerType / GetNullableInnerMarshallerName helpers, then short-circuited the IsGenericInstance path in: - EmitNativeDelegateBody parameter list (client-side method body params). - EmitClientCallReturn return value (client-side method body returns). - EmitDoAbiBodyIfSimple parameter list (server-side CCW Do_Abi_* params). - EmitDoAbiBodyIfSimple return value (server-side CCW Do_Abi_* returns). - WriteFactoryConstructorMethod parameter list (constructor / composable factory args). Each Nullable path now emits Marshaller.UnboxToManaged(value) (managed in) or Marshaller.BoxToUnmanaged(value) (managed out), matching the truth template exactly — including primitives (Int32Marshaller, UInt32Marshaller, GuidMarshaller, etc.) and value-type structs (DateTimeOffsetMarshaller, TimeSpanMarshaller, custom ABI struct marshallers). Verified: SDK now emits 477/477 UnboxToManaged and 1827/1827 BoxToUnmanaged (matching truth byte-counts). 0 references to non-existent Nullable'1Marshaller types remain in the output.

Implemented full client- side support mirroring the truth pattern. Changes: - IsSystemType helper: detects System.Type and the WinMD source type Windows.UI.Xaml.Interop.TypeName (which is mapped to System.Type). - CanEmitAbiMethodBody now allows Type as In param, Out param, and return type. - Function pointer signature uses 'global::ABI.System.Type' for Type params and 'global::ABI.System.Type*' for the return slot (instead of the placeholder int). - Client-side input setup: emits global::ABI.System.TypeMarshaller.ConvertToUnmanagedUnsafe(value, out TypeReference __value); before the call (mirroring truth's ConvertToUnmanagedUnsafe + TypeReference pattern). - Type input params now share the HString fast-path 'fixed(void* _x = ..., _y = ...)' block rather than nesting their own; the call argument is __value.ConvertToUnmanagedUnsafe() matching the truth template. - Type return value: __retval is declared as 'global::ABI.System.Type', and the return statement is return global::ABI.System.TypeMarshaller.ConvertToManaged(__retval); Verified: throw null! count dropped from 72 to 42 across XAML+Component (-30), mostly eliminating System.Type stubs (e.g. GetMetadata, RegisterAttached, SetBinding/GetBinding helpers, TargetType getter/setter). All 3 scenarios still generate the expected file counts. The remaining 42 stubs (35 Do_Abi_* server-side ReceiveArray callbacks, non-blittable struct array returns, complex struct out params, and delegate Invokes) are tracked as separate sub-categories of M2 and will be implemented in follow-up commits.

These statics interfaces are exclusive-to runtime classes (Colors, ColorHelper, FontWeights, NotifyCollectionChangedEventArgs) that are intentionally excluded from the projection because they're manually projected in WinRT.Runtime. WriteInterfaceMarshallerStub now early-exits when the interface is exclusive-to a class that is NOT included by the projection filter.

Verified: SDK GeneratedInterfaceIIDs.cs is now byte-exact with truth (7695/7695, 0 extras, 0 missing, 0 wrong values). All 6 orphan *Methods classes are eliminated.

Changes: 1. CanEmitAbiMethodBody Out param check: allow IsComplexStruct (and System.Type was already there). Same for Ref. Also added IsComplexStruct to ReceiveArray check (groundwork for later array work). 2. Function pointer signature: out complex struct emits 'global::ABI..*' (the ABI struct pointer); System.Type emits 'global::ABI.System.Type*'. 3. Local declaration for out param: complex struct uses GetAbiStructTypeName (e.g. 'global::ABI.AuthoringTest.BasicStruct'); System.Type uses 'global::ABI.System.Type'. 4. Writeback after call: complex struct out is converted via .ConvertToManaged(__local); System.Type out via global::ABI.System.TypeMarshaller.ConvertToManaged(__local). 5. needsTryFinally now includes complex struct + System.Type out params (their ABI struct backing buffers need Dispose). 6. Finally block adds Dispose calls for complex struct out (.Dispose(__local)) and System.Type out (global::ABI.System.TypeMarshaller.Dispose(__local)). Verified: AUTH throw null! drops 8 -> 7. GetStruct(out BasicStruct) now emits the truth template exactly: try { call -> *result = ...ConvertToManaged(__result); } finally { ...Dispose(__result); }.

The ABI signature for this is the standard ReceiveArray pair (uint* size, T** data), but mine was emitting the wrong function-pointer signature (double* returnValue instead of (uint*, double**)), and EmitDoAbiBodyIfSimple bailed to throw null!. Changes: 1. WriteAbiParameterTypesPointer: when a ByReferenceTypeSignature wraps an SzArrayTypeSignature and the param category is ReceiveArray, emit (uint* __Size, ElementAbiType** ) instead of (T*) — matching the truth's COM ABI signature for an out array. 2. CanEmitAbiMethodBody (in Do_Abi context): allow ReceiveArray params for blittable primitives, blittable structs, strings, runtime classes, objects, and complex structs. Also allow IsComplexStruct in PassArray/FillArray. 3. EmitDoAbiBodyIfSimple body: declare 'T[] __ = default;' before the try, zero the destination + size pointers, pass 'out __' to the inner managed call, then after the call emit the standard ConvertToUnmanaged_ UnsafeAccessor + call to copy the managed array into the ABI buffer. Verified: Do_Abi_GetBoundingRectangles_7 is now byte-identical to truth (uint* __returnValueSize, double** returnValue). XAML throw null! drops 4 -> 3, AUTH 7 -> 5.

This enables the final 2 throw null! stubs to emit real bodies: - AuthoringTest.AnotherNamespace.ProcessAndOutput (PassArray BasicStruct + ReceiveArray BasicStruct). - AuthoringTest.BasicClass.ReturnArray (PassArray BasicStruct + return BasicStruct[]). Verified: ALL 3 scenarios now have 0 throw null! stubs (was 72 originally, 72 -> 0). All 3 scenarios still produce expected file counts (SDK 328, XAML 29, Component 8). The existing PassArray non-blittable infrastructure (InlineArray16, ArrayPool, fixed-block CopyToUnmanaged + Dispose-in-finally + Free-via-UnsafeAccessor) handles the complex struct case automatically once the predicate allows it. Note: the emitted code uses 'nint' as the storage element type (matching the existing non-blittable path, which is wire-compatible with the truth's 'BasicStruct' storage on 64-bit) and '<#Windows>' as the assembly marker inside the marshaller path string. Both are functionally equivalent to the truth pattern for runtime behavior, but byte-level differences with the truth template remain (truth uses the projected struct type for storage and the type's actual assembly name in the marshaller path).

The reason: when the InterfaceImpl row points at a same-module type via TypeRef, mine fell into the TypeReference branch which always prefixed 'global::', whereas the TypeDefinition branch correctly skips the prefix when the writer's CurrentNamespace matches. Fix: WriteInterfaceTypeNameForCcw now resolves the ITypeDefOrRef to a TypeDefinition (via _cacheRef.RuntimeContext) when possible, before dispatching to the type-specific branch.

The C# port previously emitted only "by cswinrt." with no version. This change ports the same logic by: - Setting $(VersionString) on the writer csproj so the assembly's AssemblyInformationalVersionAttribute mirrors the C++ macro. - Adding CodeWriters.GetVersionString() that reads the attribute at runtime and strips the SourceLink "+" suffix so output is deterministic across rebuilds of the same source. - Updating all three banner emission sites (TypeWriter.WriteFileHeader, CodeWriters.WriteFileHeader, CodeWriters.WriteInterfaceIidsBegin) to emit "cswinrt.exe version ". Verified the SDK / XAML / Component scenarios still produce 328 / 29 / 8 files, and the banner now matches the truth output byte-for-byte (modulo the version string itself).

These would crash at runtime as soon as the corresponding constructor or delegate is invoked. The C++ tool emits real marshalling sequences in all 5 cases. The 5 stubs split into two categories: (a) Composable activation factory Invoke() bodies for constructors that take a System.Type parameter (Style(Type), PageStackEntry(Type, ...) in xaml). The Constructors.cs simple-emit gate did not allow Type parameters; add IsSystemType(pt) to the allowed list, then pre-marshal via: global::ABI.System.TypeMarshaller.ConvertToUnmanagedUnsafe(p, out TypeReference __p); fixed(void* _p = __p) { ... __p.ConvertToUnmanagedUnsafe() ... } (b) Delegate CCW Invoke stubs for delegates whose signatures involve a struct-by-value parameter, struct-by-value return, or generic-instance return (StructParamDelegate, StructReturnDelegate in authoring; ListViewKeyToItemHandler in xaml). The Abi.cs EmitDelegateInvokeBody simple-emit gate did not allow IsComplexStruct or IsGenericInstance return types and did not allow IsComplexStruct param types. Allow them and add the matching marshalling code paths: - Complex struct param: EmitMarshallerConvertToManaged(...) emits 'Marshaller.ConvertToManaged()'. - Complex struct return: EmitMarshallerConvertToUnmanaged(...) emits '* = Marshaller.ConvertToUnmanaged();'. - Generic-instance return: emit a [UnsafeAccessor]-based local ConvertToUnmanaged_ static extern, then emit '* = ConvertToUnmanaged_(null, ).DetachThisPtrUnsafe();'. Verified: total 'throw null!' stubs in generated output across the SDK (328 files), XAML (29 files), and Authoring (8 files) scenarios drop from 5 to 0. File counts unchanged.

The C# port skipped any required interface that was BCL-mapped (`if (mapped is not null && mapped.HasCustomMembersOutput) { continue; }`), which omitted the forwarders that the C++ tool emits to satisfy `IList`, `ICollection`, and `IEnumerable` queries through DIC dispatch. Without these forwarders, a `((IList)bindableVec).Count` call on an `IBindableObservableVector` RCW would have nothing to dispatch to from the DIC shim, breaking XAML data binding scenarios that walk into the non-generic collection contract. Fix: in `WriteInterfaceIdicImplMembersForRequiredInterfaces`, when the required interface is mapped (`HasCustomMembersOutput == true`), delegate emission to a new `EmitDicShimMappedBclForwarders(w, name)` helper that writes the matching set of explicit-interface DIM forwarders that all delegate through `((BclType)(WindowsRuntimeObject)this).Member`. - `IBindableVector` -> `IList` (covers IList + ICollection + IEnumerable members; pre-marks the inherited `IBindableIterable` as visited so we don't emit a duplicate `IEnumerable.GetEnumerator` forwarder). - `IBindableIterable` -> `IEnumerable` (single `GetEnumerator` forwarder). Verified: `IBindableObservableVector` shim now emits all 17 IList / ICollection / IEnumerable forwarders (1:1 with truth) and `IBindableVectorView` shim emits the single `IEnumerable.GetEnumerator` forwarder. SDK / XAML / Authoring scenarios all generate 328/29/8 files; 0 `throw null!` stubs. Build clean.

The over-emission causes substantial code bloat (in SDK alone: +1202 extra `_obj` locals, +601 `GetObjectReferenceForInterface` calls, +601 `TypeHandle` accesses, +562 `Unsafe.*` calls) and subtly changes runtime semantics: full bodies bypass the parent interface's own DIC shim, so any typemap override or alternate parent shim is ignored. Fix: split DIC member emission into two paths. - `WriteInterfaceIdicImplMembersForInterface` (existing, full bodies): used only for the SELF interface (the one declared on the file interface). Members include the full ABI dispatch sequence. - `WriteInterfaceIdicImplMembersForInheritedInterface` (new, thunks): used for every required (parent) WinRT interface walked from the self interface. Methods/properties/events all become single-line delegating thunks via `((IParent)(WindowsRuntimeObject)this).Member`. Read-only properties get expression-bodied form, read-write get the block form, events get add/remove `+=`/`-=` thunks. Verified: `IActivatedEventArgsWithUser` shim now matches truth — User (self) keeps full body; Kind, PreviousExecutionState, SplashScreen (inherited from IActivatedEventArgs) emit single-line thunks. SDK / XAML / Authoring scenarios generate 328 / 29 / 8 files; 0 throw null! stubs. Native AOT publish clean.

Two distinct gaps: (a) The TypeFilter prefix-match algorithm required matches to land at a namespace-boundary `.`, but the C++ winmd::reader::filter does pure prefix matching at the typename level. So excludes like `Windows.UI.IColorHelper` (intended to catch IColorHelperStatics, IColorHelperStatics2, etc.) failed to match. Ported the C++ `filter::match` algorithm verbatim: split the full type name into namespace + typename at the LAST '.', match the rule prefix as either a namespace-prefix or a namespace + typename-prefix. Sort rules by descending length; on tie, includes win over excludes; first matching rule decides. This matches the C++ semantics that allow the rsp's `-exclude Windows.UI.IColorHelper` to catch `Windows.UI.IColorHelperStatics2` via typename-prefix. (b) Mapped classes whose ABI is suppressed (EmitAbi=false on MappedType, e.g. NotifyCollectionChangedEventArgs) were not preventing emission of their factory/statics/default interfaces. Added two complementary skips: - In the IID emission's factory-interface collection loop (ProjectionGenerator.cs), skip mapped classes with EmitAbi=false so their factory interfaces don't enter the bypass set. - In the IID emission's main loop, skip an interface whose [ExclusiveTo] owner is a mapped class with EmitAbi=false. - In WriteInterface (CodeWriters.Interface.cs) and WriteAbiInterface (CodeWriters.Abi.cs), apply the same exclusive-to-mapped-class check to skip the projection AND the ABI types entirely. Verified: SDK output drops the 6 extra IIDs (IColorHelperStatics, IColorHelperStatics2, IColorsStatics, IFontWeightsStatics, INotifyCollectionChangedEventArgs, INotifyCollectionChangedEventArgsFactory) and the 3 extra ABI types (INotifyCollectionChangedEventArgs interface, INotifyCollectionChangedEventArgsMethods, INotifyCollectionChangedEventArgsFactoryMethods). File counts unchanged: SDK 328, XAML 29, Authoring 8. File lists are byte-identical to truth. 0 throw null! stubs. Native AOT publish clean.

The mine output produced names like `CreateInstanceWithOwner_1` where truth produced `CreateInstanceWithOwner_3`. Within the current SDK / XAML metadata the names were internally self-consistent and produced byte-equivalent IL, but using userParamCount creates a latent name-collision risk: two composable factory overloads sharing the same user-visible param count but differing in their trailing baseInterface shape would produce two classes with the same name and a compile error. Using the total ABI param count (which includes the composable `baseInterface` and `out innerInterface` params) guarantees uniqueness. Fix is a one-line change in CodeWriters.Constructors.cs: build the `callbackName` suffix from `sig.Params.Count` instead of `userParamCount`. The args struct and the callback class derive their names from `callbackName` so they update consistently. Verified: XAML's `Windows.UI.Xaml.Automation.Peers.cs` now emits `CreateInstanceWithOwner_3` (330 occurrences) matching truth's 330, and `CreateInstanceWithOwner_1` (15 occurrences) matching truth's 15.

The C++ tool always wraps the nullable-return ConvertToManaged in this pair so the 'T?' annotation on the return type is honored even if the surrounding context is '#nullable disable'. Mine relied on the outer marshaller class scope for the nullable annotation, which was usually equivalent but fragile if any intervening directive landed in the class body.

ConvertToManaged' method header and '#nullable disable' immediately after its closing brace.

Mine dropped the qualifier in the same-namespace case, e.g. 'CustomWWWMarshaller.ConvertToManaged(__retval)' instead of 'global::ABI.AuthoringTest.CustomWWWMarshaller.ConvertToManaged(__retval)'. (b) ABI struct type names (used as local-variable types, function pointer signatures, fixed pointers, casts, etc.): truth uses the short unqualified form 'BasicStruct' inside the matching ABI. namespace; mine emitted the fully-qualified 'global::ABI.AuthoringTest.BasicStruct' form everywhere. Both forms compile and resolve to the same types as long as no local-scope collision exists, but truth's policy is more defensive against future symbol additions. Fix: swap the same-namespace check between the two helpers. - GetMarshallerFullName: removed the same-namespace short-name path so it always emits 'global::ABI..Marshaller'. - GetAbiStructTypeName: added the same-namespace short-name path so it emits just '' when the writer is currently in 'ABI.'.

Root cause: the parameterless default-constructor emission path in WriteFactoryConstructors (when the type has no factory but has [Activatable(uint version)]) hardcoded ".Agile" instead of calling GetMarshalingTypeName(classType) like the factory-constructor path does. Treating an STA-bound or unknown-marshaling object as Agile bypasses the standard COM marshaller and would lead to RPC_E_WRONG_THREAD or silent thread-safety violations at runtime. Fix is a one-line change in CodeWriters.Constructors.cs: replace the hardcoded ".Agile" with a call to GetMarshalingTypeName(classType) which reads the [MarshalingBehaviorAttribute] enum value and returns the matching CreateObjectReferenceMarshalingType.* expression (2->Agile, 3->Standard, anything else -> Unknown). Verified: SDK Agile count drops from 6946 to 6897 (matches truth). DisplayRequest now correctly emits Unknown (its [MarshalingBehavior(MarshalingType.None)] = value 1, which maps to Unknown).

The actual COM object behind a static/activation factory vtable is the generated ButtonUtilsServerActivationFactory implementing the ABI.Impl.AuthoringTest.IButtonUtilsStatic interface — NOT the user runtime class. Truth correctly emits: ComInterfaceDispatch.GetInstance This was caused by the M1 'exclusiveToOwner' branch in EmitDoAbiBodyIfSimple unconditionally rewriting the dispatch target to the runtime class for ALL exclusive-to interfaces in component mode. That works for instance interfaces (the user class IS the CCW target for instance methods), but is wrong for static and activation factory interfaces (the activation factory's generated ABI.Impl interface is the CCW target). Fix: in EmitDoAbiBodyIfSimple (CodeWriters.Abi.cs), add a check that walks the exclusive-to class's [Static] and [Activatable] attributes to see if the current interface is registered as a static/factory interface. If yes, emit the dispatch target as 'global::ABI.Impl..' instead of the runtime class. Verified: AuthoringTest.cs now matches truth's 34 ABI.Impl static/ factory dispatch sites byte-for-byte.

The add/remove thunks retrieve __this via ComInterfaceDispatch.GetInstance (after V3-M1) and pass it to _Event.GetOrCreateValue(__this), so the table type must use the same dispatch target type. Truth uses the concrete user runtime class as TKey (e.g. ConditionalWeakTable). Fix: pass the already-computed ifaceFullName from EmitDoAbiBodyIfSimple into EmitEventTableField as the table key type, instead of recomputing it from the WinRT ABI interface (which projects to the ABI.Impl form in component mode for exclusive-to interfaces). This naturally inherits the V3-M1 fix's distinguishing of static/factory vs instance interfaces: - Instance event on a user class -> TKey = user class - Event on a static/factory interface -> TKey = ABI.Impl interface Verified: AuthoringTest.cs's _ComplexDelegateEvent on BasicClass now emits ConditionalWeakTable matching truth byte-for-byte.

The accessor binds against an exact metadata-name match in WinRT.Interop, so the wrong token would fail accessor resolution at runtime. 2) Data-pointer parameters used 'void**' instead of '*' for complex-struct elements. The wrong layout type would have produced silent memory corruption when the marshaller copied data, since value-type arrays are contiguous blocks of struct elements, not buffers of pointers. 3) Inline buffers used 'Span'/'nint[]' instead of 'Span'/'T[]' and the ArrayPool storage type was 'nint' instead of ''. Two additional follow-on bugs that surfaced after fixing the above: - '___data' declaration for ReceiveArray used 'int*' instead of '*'. - ConvertToManaged_ and Free_ for ReceiveArray params hardcoded 'ABI.System.<...>' as the marshaller namespace and didn't handle complex structs at all (only IsAnyStruct + primitive). Fixes in CodeWriters.Abi.cs (authoring-affecting, idempotent for SDK): - EncodeArrayElementForTypeDef: pass the type to GetInteropAssemblyMarker so third-party / component types resolve to '' instead of defaulting to '<#Windows>'. - 4 sites that emit InlineArray16/ArrayPool storage for non-blittable PassArray/FillArray params: extend storageT/poolStorageT/dataParamType selection to handle IsComplexStruct (use ABI struct type) in addition to IsMappedAbiValueType. - Fixed-block opener for non-blittable PassArray: emit 'fixed(* _x = ...)' for complex structs (no cast needed on the call site). - Dispose_ + ArrayPool return for non-blittable PassArray: same treatment. - CopyToManaged_ for non-blittable FillArray: same treatment. - ConvertToManaged_ + Free_ for ReceiveArray params: replace hardcoded 'ABI.System.<...>' marshaller namespace with GetArrayMarshallerInteropPath() and add complex-struct + ref-type cases for elementAbi. - '___data' declaration for ReceiveArray: same elementAbi categorization (void* / ABI struct / blittable struct / primitive). Verified: 0 occurrences of '#Windows' tokens, 'ABI.System.<' mis-prefixes, 'void** data', or 'ArrayPool' in authored output. SDK / XAML / Authoring all generate 328 / 29 / 8 files; 0 throw null! stubs.

But the call site has a special-case for IsNullableT(rt) that uses 'Marshaller.BoxToUnmanaged' instead of the generic UnsafeAccessor. The hoisted declaration was therefore unused dead code (and would have produced CS8321 warnings). Fix: in EmitDoAbiBodyIfSimple, gate the M1 hoisted UnsafeAccessor on 'returnIsGenericInstance && !IsNullableT(rt)'. Verified: AuthoringTest.cs no longer emits the unused 'static extern WindowsRuntimeObjectReferenceValue ConvertToUnmanaged_(...Nullable'1Marshaller...)' declaration.

The previous round's blanket "skip exclusive-to interfaces of mapped classes with EmitAbi=false" rule was too aggressive — it correctly suppressed INotifyCollectionChangedEventArgs (whose IIDs come from the runtime's WellKnownXamlInterfaceIIDs) but also incorrectly suppressed IUriRuntimeClass and IPropertyChangedEventArgs. Fix: introduce a more targeted MappedType.SuppressExclusiveInterfaces flag (default false) and set it only on the few mapped runtime classes whose [ExclusiveTo]-related interface family must be excluded: - Microsoft.UI.Xaml.Data.DataErrorsChangedEventArgs - Microsoft.UI.Xaml.Interop.NotifyCollectionChangedEventArgs - Windows.UI.Xaml.Data.DataErrorsChangedEventArgs - Windows.UI.Xaml.Interop.NotifyCollectionChangedEventArgs These four classes have their IIDs (and the class's own IID, plus the factory's IID) supplied by WindowsRuntime.InteropServices.WellKnownXamlInterfaceIIDs; emitting them in the generated projection would create duplicate entries. Re-add the V3-M4 round-2 exclusion check in the same three places (ProjectionGenerator.cs IID emission loop, CodeWriters.Abi.cs WriteAbiInterface, CodeWriters.Interface.cs WriteInterface) but key on SuppressExclusiveInterfaces instead of !EmitAbi. Verified: - SDK: emits IUriRuntimeClass + IUriRuntimeClassFactory + IUriRuntimeClassWithAbsoluteCanonicalUri (matches truth); does not emit INotifyCollectionChangedEventArgs (matches truth). - XAML: emits IPropertyChangedEventArgs (matches truth); does not emit INotifyCollectionChangedEventArgs / DataErrorsChangedEventArgs. - 328 / 29 / 8 files; 0 throw null! stubs.

Truth uses the unqualified 'BasicStructMarshaller.X(...)' form when the marshaller's ABI namespace matches the writer's current ABI namespace. This was caused by the M8 fix from the previous round, which changed GetMarshallerFullName to ALWAYS qualify. That was over-broad — for authored marshallers in the same ABI sub-namespace, truth uses the short form. Fix: re-add the same-namespace short-name path in GetMarshallerFullName. The qualifier is dropped only when w.InAbiNamespace == true and w.CurrentNamespace == ns (after mapped-type remapping). All other call sites still use the fully-qualified form. Verified: AuthoringTest.cs marshaller calls inside 'ABI.AuthoringTest' namespace now emit the short form (e.g. 'BasicStructMarshaller.ConvertToManaged(...)'). Cross-namespace calls (e.g. 'global::ABI.System.Int32Marshaller.X(...)' from inside 'ABI.AuthoringTest') still use the fully-qualified form. SDK / XAML / Authoring all generate 328 / 29 / 8 files; 0 throw null!. NOTE: V3-M11 part 2 (drop global:: on BCL types in scope via using directives) is deferred. It requires per-call-site context awareness in the type-name writer that's mixed across multiple emission paths and risks regressions. The qualified form mine emits is semantically identical and more defensive against future symbol additions.

Emitted "PowerThermalChannelDataMarshaller.ConvertToUnmanaged(unboxedValue)" which doesn't exist - only BoxToUnmanaged/UnboxToManaged exist on this marshaller (compile error) Fix: Add a System.Guid / IntPtr / UIntPtr early-return to IsFieldTypeBlittable. These three are the cross-module fundamental value types not covered by the CorLibTypeSignature branch. Verified: PowerThermalChannel{Data,Id} ReferenceImpl now uses the direct cast and write pattern matching truth. Mine "ConvertToUnmanaged(unboxedValue)" count drops from 72 to 70, matching truth exactly. The two extra mirror struct declarations are gone. All 3 scenarios still build to 328 / 29 / 8 files; 0 throw null! stubs.

ObjRef field definitions 2. Event source definitions 3. ObjectReference constructor 4. Activator/composer constructors (write_attributed_types) 5. Conditional finalizer 6. HasUnwrappableNativeObjectReference <- HOOKS HERE 7. IsOverridableInterface <- HOOKS HERE 8. write_class_members (instance + static members) R2-M9 (committed as 6ae00fd4) had moved the hooks to the bottom, after all members. That was an over-correction: at the time, my earlier sampling was misled by a few outlier classes where the hooks appeared late due to interleaved statics. With the full validation in v3-r3, agents independently confirmed the C++ pattern matches truth in ~67% of classes (2210/3318) with hooks early. Fix: revert R2-M9. Move the HasUnwrappableNativeObjectReference and IsOverridableInterface emission in WriteClass to BEFORE WriteClassMembers + WriteStaticClassMembers, matching the C++ order.

Mine was emitting "__Length" in 7 emission sites in EmitDoAbiBodyIfSimple and AppendCcwParameters. The output ABI sizes (e.g. "____return_value__Size") were already emitted with the "Size" suffix - the inconsistency was specifically in the input-array length parameter names. This produced an inconsistency within mine's own output (some "Size" identifiers, some "Length" identifiers in the same method) and a divergence from truth.

The actual call sites later in the body just reference the already-declared accessor (see code_writers.h:8128-8138 - all marshaller decls are emitted first via write_convert_to_managed_function + write_convert_to_unmanaged_function). Mine had hoisted the ConvertToUnmanaged decl for generic-instance return types (V3-M12 / R2-M12 commit), but had left the [UnsafeAccessor] decl inline (inside the try block) for two other cases: 1. ReceiveArray params (out T[]): the post-call ConvertToUnmanaged_ 2. Return-array case (T[] return): the post-call ConvertToUnmanaged_ For these, the [UnsafeAccessor] decl was emitted alongside the call inside the try block. This works because static local functions can be declared anywhere in the method body, but it differs from truth. Fix: extend the existing hoist section (right after the generic-instance hoist) to also emit [UnsafeAccessor] decls for ReceiveArray params and return-array. Keep the actual ConvertToUnmanaged_(...) call where it was (inside the try block). Verified: AuthoringTest.cs Do_Abi_ReturnArray_14 now emits "ConvertToUnmanaged___return_value__" decl at the very top of the method body (matching truth lines 4256-4257), and the call "ConvertToUnmanaged___return_value__(null, ____return_value__, ...)" remains inside the try block at the bottom (matching truth line 4282).

Ref params and complex-struct PassArrays use separate typed fixed lines (no braces) BEFORE the combined block - in C# multiple chained "fixed(...)" without braces share the body of the next braced block. See write_abi_invoke at code_writers.h:6682+. Mine had been emitting one combined fixed only for input strings + Type params, then separately opening a new fixed block per PassArray and per Ref param, producing deeply nested fixed blocks. Fix: in EmitAbiMethodBodyIfSimple, restructure the fixed-block emission: 1. Emit typed-pointer fixed lines for Ref params (no braces). 2. Emit ONE combined "fixed(void* _a, _b, ...)" block containing all pinnable inputs: strings, Type[], and ALL PassArray spans (including complex structs - matching truth, which uses void* + (T*) cast for the CopyToUnmanaged path even on authored types). 3. Inside the block body, emit HStringMarshaller calls and CopyToUnmanaged calls. Also revert V3-M2 partial change: complex-struct PassArrays in the CopyToUnmanaged main call path now use void* fixed + (T*) cast at the call site (matching truth), rather than typed pointer with no cast. The Dispose path inside the finally block continues to use the typed pointer (matches truth's Dispose pattern). Verified: SDK Windows.AI.Actions.cs CreateArrayEntityWithCustomKind now emits "fixed(void* _customKind = customKind, _entities = __entities_span)" combined block matching truth exactly. AuthoringTest.cs ReturnArray emits "fixed(void* _basicStructs)" + "CopyToUnmanaged_basicStructs(..., (BasicStruct*)_basicStructs)" matching truth, while the Dispose path keeps "fixed(BasicStruct* _basicStructs)" typed pointer.

Mine's WriteInterfaceIdicImplMembersForRequiredInterfaces was skipping IObservableMap`2 and IObservableVector`1 because they: 1. Have non-null mapped entries but with HasCustomMembersOutput=false (they retain WinRT names since the BCL has no equivalent) 2. Have unbound generic parameters - mine's "if generic, skip" path bailed. Result: IPropertySet emitted an empty body (its only direct interface is IObservableMap), and ICollectionView ended after its own WinRT-direct members (its only interesting parent is IObservableVector). Fix: 1. Add specific Windows.Foundation.Collections.IObservableMap`2 / IObservableVector`1 detection BEFORE the "skip if generic" check. 2. Extract the concrete type arguments from the InterfaceImplementation's TypeSpecification.Signature (GenericInstanceTypeSignature). 3. Call new helpers EmitDicShimIObservableMapForwarders / EmitDicShimIObservableVectorForwarders that emit the explicit-impl dictionary/list forwarders + the MapChanged/VectorChanged event, mirroring C++ write_dictionary_members_using_idic / write_list_members_using_idic. 4. Mark deeper inherited generics (IMap`2, IVector`1, IIterable`1) as visited to avoid re-emission.

This emits the zero-allocation pattern: fixed(void* _x = x) { HStringMarshaller.ConvertToUnmanagedUnsafe((char*)_x, x?.Length, out HStringReference __x); RestrictedErrorInfo.ThrowExceptionForHR(abiInvoke(ThisPtr, __x.HString)); } Mine's EmitNativeDelegateBody emitted the heap-allocating slow path: void* __x = default; try { __x = HStringMarshaller.ConvertToUnmanaged(x); ... } finally { HStringMarshaller.Free(__x); } This forced an HSTRING heap allocation + free on every delegate Invoke, which adds up significantly on hot event-firing paths. Behavior was correct but performance regressed. Fix: in EmitNativeDelegateBody, restructure string param handling: 1. Drop the "void* __ = default;" heap-local declarations. 2. Drop "hasStringParams" from needsTryFinally trigger (the fast path does not need a try/finally for input strings). 3. Drop the slow-path "__ = ConvertToUnmanaged();" emission before the try block. 4. Open ONE combined "fixed(void* _a = a, _b = b, ...)" block at the call site (combines both string and PassArray pinnables, mirroring the V3R3-M14 pattern for the regular ABI method body). 5. Inside the block, emit one "HStringMarshaller.ConvertToUnmanagedUnsafe((char*)_, x?.Length, out HStringReference __);" per string input. 6. Pass "__.HString" to the function pointer call (was "__"). 7. Drop the "HStringMarshaller.Free(__);" calls from the finally block (no-op for HStringReference - it's stack-only).

Root cause: the V3R4-M10 inlined per-interface GetInterface() emission used impl.Interface directly without applying the InstantiateGenericTypes substitution that the parent generic instance context (currentInstance) provides. Mirrors C++ code_writers.h:4234-4393 where for_typedef pushes a generic_args guard onto the writer stack so all subsequent write_type_name calls see substituted args. Fix: compute the substituted ITypeDefOrRef BEFORE the GetInterface() emission and the GetObjRefName call, and use it consistently throughout the iteration body. R5-M2 (CRITICAL): missing IWindowsRuntimeInterface>.GetInterface() implementations (~90 missing across 33 SDK + 5 XAML files; CS0535 errors). The IIterable subsumption pre-pass marked IIterable as 'covered' by IVector/IMap because their stub bodies included GetEnumerator. But the per-interface GetInterface() emission in WriteInterfaceMembersRecursive was also skipped. Fix: remove the IIterable subsumption pre-pass entirely (and the related MarkCoveredMappedInterfaces helper). Instead, mirror C++ exactly by NOT emitting GetEnumerator in the IList/IDictionary/IReadOnlyList/IReadOnlyDictionary stubs (matches C++ write_*_members_using_static_abi_methods which never include GetEnumerator). IIterable is then processed normally via the recursion and emits both its own GetInterface() and its GetEnumerator stubs through EmitGenericEnumerable. Same fix applied to EmitNonGenericList for symmetry with write_nongeneric_list_members_using_static_abi_methods (IBindableVector path). R5-M4 (MEDIUM): IReadOnlyDictionary's [UnsafeAccessor] extern signatures for Keys/Values used IEnumerable instead of ICollection. The runtime helper returns ICollection (because IDictionary.Keys does), so the extern must match. Public properties continue returning IEnumerable (the BCL contract) via implicit interface conversion. Mirrors C++ write_readonlydictionary stubs. Validated end-to-end: all 3 scenarios (SDK 328, XAML 29, Authoring 8 files) generate cleanly. Verified PropertySet now emits all 4 GetInterface() impls matching truth (IPropertySet, IObservableMap, IDictionary, IEnumerable>). HttpChallengeHeaderValueCollection: mine 16 IEnumerable.GetInterface() impls matches truth 16. Total IEnumerable.GetInterface count: SDK 78=78, XAML 30=30. Zero T0/T1 placeholder leaks in any scenario.

The internal RCW-wrapping ctor and the four base-chaining ctors used by derived projected types already emitted it correctly. Without this fix, the finalizer's GC.RemoveMemoryPressure(N) was unbalanced for activation-factory-constructed instances — the GC would see a Remove without a matching Add, causing memory pressure underflow. The runtime would not run the GC aggressively enough for these large native-backed objects (VideoFrame at 1.2MB, SoftwareBitmap, MediaComposition / MediaOverlay / MediaOverlayLayer). For high-frequency creation patterns (media pipelines, camera capture), native memory could accumulate excessively before GC triggers. Mirrors C++ write_factory_constructors at code_writers.h:2851-2922 which emits GC.AddMemoryPressure(N) in BOTH the factory-method ctor branch (line 2895-2896) and the parameterless activation ctor branch (line 2919-2920). Validated end-to-end: SDK GC.AddMemoryPressure() count matches truth exactly (31=31 across all files; per-file: Windows.Media.cs 4=4, Windows.Graphics.Imaging.cs 4=4, Windows.Media.Editing.cs 11=11). XAML and authoring scenarios unchanged (no [GCPressure] in those projections).

The matching getter correctly returns 'T[]' (the property type), and the user-facing public class setter still takes 'T[]' (the property API), but the internal ABI helper setter parameter convention is ReadOnlySpan — matching the pass_array calling convention used elsewhere. Affected ABI helpers: 5 setters across 3 files — - Windows.Security.Cryptography.Certificates.cs: Value, Thumbprint, CurveParameters - Windows.ApplicationModel.DataTransfer.cs: AllowedTargetAppIds - Windows.Media.Protection.PlayReady.cs: MeteringCertificate Two-part fix: 1. WriteProjectedSignature: when isParameter=true and the type is SzArrayTypeSignature, emit 'ReadOnlySpan' instead of 'T[]'. Mirrors C++ write_projected_signature at code_writers.h:822-834. 2. ABI setter site (CodeWriters.Abi.cs): call WritePropType(w, prop, isSetProperty: true) for the setter parameter so the SZ-array branch is exercised. Mirrors C++ code_writers.h:7193 which uses write_prop_type(w, prop, true) for the setter param. Generator body unchanged: 'fixed (void* _value = value)' works identically for both T[] and ReadOnlySpan via GetPinnableReference. Validated end-to-end: SDK setter signatures match truth exactly (3 + 1 + 4 = 8 ReadOnlySpan setters across the 3 affected files). Zero T[] setter signatures remain in those files.

From 92dfc20647d75f382d11cc0a861359a3f44c1bd1 Mon Sep 17 00:00:00 2001 From: Sergio Pedri Date: Mon, 4 May 2026 10:40:45 -0700 Subject: [PATCH 249/320] Fix IsTypeBlittable: honor mapped struct's RequiresMarshaling flag MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The IsTypeBlittable helper was walking struct fields to determine blittability without first checking whether the struct itself has a mapped-type entry. This caused 3 XAML structs (Duration, KeyTime, RepeatBehavior) to be incorrectly classified as non-blittable, producing broken get_Value emissions in their ReferenceImpl classes: Duration value = DurationMarshaller.ConvertToUnmanaged(unboxedValue); *(Duration*)result = value; ConvertToUnmanaged doesn't exist on DurationMarshaller (which is the blittable shape with only BoxToUnmanaged/UnboxToManaged), and the unqualified 'Duration' identifier wasn't in scope. Result: 18 compile errors across Windows.UI.Xaml.cs and Windows.UI.Xaml.Media.Animation.cs (CS0117 + CS0246 in 3 sites). Root cause: Duration/KeyTime/RepeatBehavior all have a TimeSpan field. Our TimeSpan mapping correctly has RequiresMarshaling=true (because it maps WinRT TimeSpan to System.TimeSpan, which need a 64-bit conversion at the ABI). But the parent structs themselves are self-mapped with RequiresMarshaling=false (meaning they pass through the ABI as-is). The C++ tool's is_type_blittable checks the struct's own get_mapped_type FIRST and returns !requires_marshaling if mapped (code_writers.h:81-124, struct_type branch); only when not mapped does it walk fields. My port skipped the parent-struct mapping check and went straight to field walking, where the TimeSpan field's RequiresMarshaling=true flag (correctly) propagated to misclassify the parent struct. Fix: add the MappedTypes.Get(...).RequiresMarshaling check at the start of the struct branch, mirroring the C++ tool 1:1. Validated end-to-end via standalone csproj that compiles only the generated sources against WinRT.Runtime.dll: - Pre-fix XAML: 18 errors (CS0117/CS0246 across 6 line locations in 2 files). - Post-fix SDK: 0 errors, 164 warnings (all CS8625 nullability on emitted '(null)' UnsafeAccessor args; identical to truth byte-for-byte). - Post-fix XAML: 0 errors, 124 warnings (same CS8625 pattern). - Post-fix Auth: 0 errors, 0 throw null! stubs (unchanged). - Duration / KeyTime / RepeatBehavior: 0=0=0 Marshaller.ConvertToUnmanaged calls vs truth (was 1+1+1 in mine). Duration's get_Value body now matches truth byte-for-byte: 'var value = (Duration)..; *(Duration*)result = value;'. Other self-mapped XAML structs that were previously fine remain fine (CornerRadius, GridLength, Thickness, Matrix3D — their fields are pure doubles so the field-walk path coincidentally produced the right answer).

Methods/properties with this attribute are contractually guaranteed to return S_OK, so the wrap is redundant. My port was always emitting the wrap unconditionally, ignoring the attribute. Affected sites in SDK: 3 properties total (all in Windows.UI.UIAutomation): - Windows.UI.UIAutomation.cs : IAutomationConnection.IsRemoteSystem - Windows.UI.UIAutomation.cs : IAutomationElement.IsRemoteSystem - Windows.UI.UIAutomation.Core.cs : ICoreAutomationConnectionBoundObjectProvider.IsComThreadingRequired Zero correctness impact in the pre-fix output (the extra wrap is a benign no-op for noexcept methods since HRESULT is always S_OK), but the ThrowExceptionForHR call is a real branch on every property read. Removing the wrap matches truth byte-for-byte and shaves ~1 instruction per call. Implementation: added an isNoExcept parameter to EmitAbiMethodBodyIfSimple, threaded through from WriteStaticAbiMethods. For methods, the flag is Helpers.IsNoExcept(method); for properties, the flag is Helpers.IsNoExcept(prop) applied to BOTH accessors (the attribute lives on the property, not on the individual accessors -- matches helpers.h:46-49). The IsNoExcept helpers were already implemented but unused. Mirrors C++ code_writers.h:6725 (the has_noexcept_attr branch). Validated end-to-end: - Mine SDK now has 3 unwrapped vtable calls matching truth's 3 (same files, same lines modulo whitespace). XAML and Auth still 0=0 (no NoException attributes in those scenarios). - IsRemoteSystem body now matches truth byte-for-byte. - Standalone-csproj build of all 3 generated source trees succeeds with 0 errors. SDK 164 + XAML 124 CS8625 nullability warnings remain (inherent to the (null) UnsafeAccessor pattern; identical to truth).

Mine emitted the type-level skeleton (class declarations, attributes, base interface lists) correctly, but the entire member-body emission pipeline was missing for ref mode, and impl-mode bodies leaked into the static factory accessor / activation callback sites that should be 'throw null;' stubs. Pre-fix structural deltas (mine vs truth, SDK): - '=> throw null' : 0 vs 26,570 (-26,570 missing) - '{ throw null; }' : 0 vs 2,642 (-2,642 missing) - 'public event ' : 0 vs 1,019 (-1,019 missing) - '[UnsafeAccessor' : 110 vs 1,712 (-1,602 missing) - 'static extern ' : 55 vs 856 (-801 missing) - 'NativeObjectReference.As(' : 0 vs 2,269 (-2,269 missing) - 'WindowsRuntimeObjectReference.GetActivationFactory(' : 1,845 vs 15 (+1,830 leaked impl) Post-fix: ALL structural counts match truth exactly across SDK and XAML. Implementation - changes per emission site: 1. WriteClassObjRefDefinitions (CodeWriters.ObjRefs.cs): - Removed early return in ref mode. Per-interface _objRef_* getters keep their full lazy MakeObjectReference + NativeObjectReference.As(IID_X(null)) bodies in BOTH modes (no settings.reference_projection gate in C++). 2. WriteClassMembers (CodeWriters.ClassMembers.cs): - Removed early return in ref mode. - Gated 'IWindowsRuntimeInterface.GetInterface()' emission with '!w.Settings.ReferenceProjection' (mirrors C++ code_writers.h:4257). - 'internal new GetDefaultInterface()' helper kept in both modes (referenced by overrides on derived classes). - Mapped IList/IDictionary/etc. stub members keep full bodies in both modes (the [UnsafeAccessor] indirection means the ref assembly doesn't actually link to the ABI types). - Non-mapped instance method bodies become '=> throw null;' in ref mode (mirrors C++ write_abi_static_method_call + write_unsafe_accessor_static_method_call, code_writers.h:1637, 1653). - Property accessor bodies become '=> throw null;' in ref mode for both expression-body and accessor-block forms (mirrors code_writers.h:1669, 1683, 1697). - Event _eventSource_* backing field emission skipped entirely in ref mode. - Event accessor bodies become 'add => throw null;' / 'remove => throw null;' in ref mode (mirrors code_writers.h:2215, 2238). 3. WriteStaticFactoryObjRef (CodeWriters.Class.cs): - Body becomes 'get { throw null; }' in ref mode (mirrors C++ write_static_objref_definition, code_writers.h:2789). 4. WriteAttributedTypes activation _objRef_ (CodeWriters.Constructors.cs): - Body becomes 'get { throw null; }' in ref mode (mirrors C++ write_activation_factory_objref_definition, code_writers.h:2748). 5. WriteStaticClassMembers (CodeWriters.Class.cs): - Static method/property/event bodies become '=> throw null;' / 'add => throw null; remove => throw null;' in ref mode. 6. EmitFactoryCallbackClass (CodeWriters.Constructors.cs): - Activation callback Invoke body becomes 'throw null;' in ref mode (mirrors C++ at code_writers.h:6849). 7. WriteComposableConstructors (CodeWriters.Constructors.cs): - Composable parameterized ctors STILL emitted in ref mode. Only the args struct + callback class are skipped (mirrors C++ write_static_composing_factory_method, code_writers.h:6886). The public ctor body references the elided types - fine for ref assemblies since bodies aren't required to compile cleanly. 8. WriteClass (CodeWriters.Class.cs): - In ref mode, when no public ctors will be emitted (no Activatable factory, and no Composable factory with methods), emit 'private TypeName() { throw null; }' to suppress the C# compiler's implicit public default constructor (mirrors C++ at code_writers.h:9519-9538). Composable factories with 0 methods don't count as having ctors (matches C++ check 'factory.composable && factory.type && factory.type.MethodList().size() > 0').

From 2939885a768e216190c875c8b05cc46f7c544261 Mon Sep 17 00:00:00 2001 From: Sergio Pedri Date: Mon, 4 May 2026 15:50:13 -0700 Subject: [PATCH 253/320] Emit per-member [SupportedOSPlatform] in reference projection mode Mirrors C++ cswinrt's per-member ContractVersion -> SupportedOSPlatform emission for reference projections. Previously, ref projections only had SOSP attributes at the type level (carried through WriteCustomAttributes); methods, properties, events, enum fields, and factory constructors did not get their per-interface SOSP attributes, causing ~3,800 missing attributes vs the C++ truth output. Fixes (mirror C++ code_writers.h): * Add writer-scoped CheckPlatform/Platform fields to TypeWriter (mirrors C++ writer::_check_platform / _platform). Set on entry to WriteClass and WriteStaticClass via try/finally guard, mirrors C++ write_platform_guard at line 9470. * GetPlatform now consults the writer state to suppress same/lower platforms within a class scope (C++ get_platform at line 2515-2525). * WriteEnum: emit per-field WritePlatformAttribute for each enum value (C++ write_enum line 10106 bind). * WriteInterfaceMembers: compute per-interface platformAttribute via WriteTemp; emit before each method, before the explicit interface impl method (overridable), and before each event (C++ line 4290-4293). * PropertyAccessorState: split single PlatformAttribute into per-accessor GetterPlatformAttribute / SetterPlatformAttribute. Property emission uses C++ collapse logic (code_writers.h:2041-2046): if both accessor platforms match, emit once at property level; otherwise emit per-accessor. * WriteStaticClassMembers: compute per-static-iface platformAttribute; emit before each static method, event, and property (with same collapse-or-split logic for static properties). Mirrors C++ line 3315. * WriteFactoryConstructors and WriteComposableConstructors: emit platformAttribute before each generated public ctor (C++ line 2861, 3167). * GetPlatform string handling: AsmResolver returns Utf8String for custom-attribute string args, not System.String -- handle by falling back to ToString().

M1: Missing 'internal new GetDefaultInterface()' for unsealed runtime classes whose default interface is non-exclusive-to (ref-projection mode) In CodeWriters.ClassMembers.cs the else-if condition emitting the 'internal new GetDefaultInterface()' helper had an extra '&& TypeCategorization.IsExclusiveTo(ifaceType)' clause not present in the C++ source (code_writers.h:4263-4280). In ref-projection mode the prior 'IWindowsRuntimeInterface.GetInterface()' branch is gated off, so the else-if is the only branch that emits the helper -- with the extra clause, unsealed classes whose default interface is a non-exclusive generic foundation collection (e.g. IObservableVector on DependencyObjectCollection) silently lost the helper. Removed the IsExclusiveTo clause to match the C++ behavior. In non-ref mode the prior branch's IsInterfaceInInheritanceList check still routes non-exclusive default interfaces to the GetInterface() branch first, so this change is a no-op for impl mode. Result: XAML ref GetDefaultInterface count 305 -> 306 (matches truth). M2: '_AddPair' helper renamed to '_Add' to match C++ overload-by-signature In CodeWriters.MappedInterfaceStubs.cs the IDictionary stubs renamed the KVP-overload Add helper to 'AddPair' to avoid C# overloading. The C++ source uses C# overload-by-signature with the same name 'Add' for both Add(K,V) and Add(KVP) extern declarations. Both forms produce identical metadata (the [UnsafeAccessor(Name = "Add")] is what the runtime uses), but the deviation broke 1:1 fidelity with C++ at 40 sites (20 declarations + 20 call sites across 14 files). Changed both lines to use the '_Add' name directly. The Remove(KVP) helper already used overloading correctly with '_Remove'. Result: '_AddPair' count 40 -> 0 across all files. M3: Emit 'new' modifier on hiding interface properties In CodeWriters.Interface.cs WriteInterfaceMemberSignatures hardcoded 'newKeyword = string.Empty' with a comment that base interface lookup was skipped. The C++ source (code_writers.h:5642) emits 'new ' when: !getter && setter && find_property_interface(w, type, prop.Name).second i.e., for setter-only properties whose name exists in any base interface. Without the modifier, C# emits CS0108 warnings on the 11 affected sites (2 in IAppointmentCalendar2, 9 in IChatMessage2), which can break builds under warnings-as-errors. Implemented FindPropertyInBaseInterfaces as a recursive walk of the interface's InterfaceImpl collection (mirrors C++ find_property_interface at code_writers.h:4154-4185), using ResolveInterface to get the base TypeDefinition and a HashSet to dedupe the visit set. Result: 11 'new { get; set; }' patterns now emitted in SDK (matches truth count). Standalone projection build emits 0 CS0108 warnings (was 11 before this fix).

The tool is a thin wrapper over WinRT.Projection.Generator.Writer's ProjectionWriter public API: parse args from a response file, build ProjectionWriterOptions, call ProjectionWriter.Run() to emit C# sources. The tool covers every flag the OLD CsWinRTGenerateProjection target sends today, including CsWinRT 3.0 leftovers that are kept for first-PR parity (--internal, --embedded, --public-enums).

Pure mechanical swap: every existing MSBuild property, the two-pass (public + private) structure, the response file writes, the OnError cleanup, the CsWinRTContinueOnError design-time-build resilience semantics, and all dead-but-still-plumbed CsWinRT 2.x flags (CsWinRTEmbedded, CsWinRTEmbeddedPublicEnums, CsWinRTPrivateProjection) are preserved as-is. Plumbing additions in Microsoft.Windows.CsWinRT.targets: * '' for RunCsWinRTProjectionRefGenerator, using the existing $(CsWinRTGenTasksAssembly) (set in the imported CsWinRTGen.targets). * New '_ResolveCsWinRToolsDirectory' dependency on the target so '_CsWinRTToolsDirectory' is computed before the new task runs. * New 'CsWinRTGenTasksAssembly' added to target Inputs so changes to the task DLL trigger an incremental rebuild (replaces the old reference to '$(CsWinRTExe)' which is no longer used; the corresponding UpToDateCheckInput entry is also updated). * Reconstruct the include/exclude/input lists for the new task from the historical CsWinRTFilters/CsWinRTPrivateFilters multi-line strings. Some in-repo projects (Windows.csproj/Windows.UI.Xaml.csproj/ WinAppSDK.csproj) set CsWinRTFilters directly with raw cswinrt.exe-style '-include X' / '-exclude Y' directives; others rely on the default item-based computation via CsWinRTIncludeItems/CsWinRTExcludeItems. Parsing the final filter strings back into items handles both cases uniformly. * Auto-add 'WindowsRuntime.Internal' include and the matching interop metadata WinMD when the user requested the 'Windows' namespace, mirroring the historical CsWinRTIncludeWinRTInterop / CsWinRTPrivateIncludeWinRTInterop behavior. Plumbing additions in Microsoft.Windows.CsWinRT.CsWinRTGen.targets: * New 'CsWinRTRefGenEffectiveToolsDirectory' default in '_ResolveCsWinRToolsDirectory'. Defaults to '$(_CsWinRTToolsDirectory)' for NuGet consumers; source-build infrastructure (next commit) overrides it to point at the source-tree build output of the new generator project. The historical CsWinRTParams / CsWinRTPrivateParams properties and '' calls for cswinrt.rsp / cswinrt_internal.rsp are kept intact: the .rsp files now serve as debug artifacts and as up-to-date check stamps (Outputs of the target). The historical CsWinRTCommand / CsWinRTCommandPrivateProjection are kept defined but no longer used by any ''; they remain harmless until the cleanup follow-up PR.

Mirrors the existing CsWinRTMergedProjectionEffectiveToolsDirectory pattern. * src/Projections/Directory.Build.targets: add a global '' to WinRT.Projection.Ref.Generator with ReferenceOutputAssembly=false, so all projection projects under src/Projections/ ensure the generator is built before their CsWinRTGenerateProjection target runs (the cswinrt.slnx already lists the project, but the per-project ProjectReference makes the dependency explicit for individual project builds too). * nuget/Microsoft.Windows.CsWinRT.nuspec: package the new tool's x64 and arm64 binaries at tools/win-x64/ and tools/win-arm64/. * src/build.cmd: collect the new tool's published-AOT binary path into cswinrtprojectionrefgen_x64 / cswinrtprojectionrefgen_arm64 variables and forward them to the nuget pack invocation. The cswinrt.slnx already includes the project entry; no .slnx change needed beyond what the user already added.

The expansion is a thin pre-processing step over ProjectionWriterOptions.InputPaths and is functionally part of the writer's public API contract, so the natural home is the writer library. Promote the type to public, move it to WinRT.Projection.Generator.Writer/Helpers/, and delete the two duplicate copies in the consumer projects.

Root cause: the writer was emitting the same type twice in the generated WindowsRuntime.Internal.cs. Two underlying duplicate-input scenarios: 1. The same physical .winmd file is referenced via two different but equivalent path strings (e.g. one absolute and one with a directory scan that picks up the same file, or two paths with different normalization). The 'winmdFiles' List in MetadataCache.Load had no dedup, so AsmResolver loaded the same module twice and the same TypeDefinition instance was added twice to NamespaceMembers.Types. 2. Multiple distinct .winmd files legitimately define types with the same full name (the CI repro: WindowsRuntime.Internal.winmd and cswinrt.winmd both define WindowsRuntime.Internal.IAccountsSettingsPaneInterop -- cswinrt.winmd re-exports the interop interfaces). The C++ cswinrt tool silently dedupes via 'std::map' in its cache; the C# port's underlying 'List' didn't, so each definition was added separately and emitted twice. Fix at two levels: 1. MetadataCache.Load: dedupe the input file list by canonical absolute path (Path.GetFullPath + OrdinalIgnoreCase HashSet) before loading, so the same physical file passed via two different path strings is only loaded once. Catches the directory-scan-overlaps-explicit-file case and the relative-vs-absolute case. 2. MetadataCache.LoadFile: dedupe by full type name. If the same namespace.name has already been registered, skip it (first-load-wins, matching C++ std::map insert semantics). This is the fix that mirrors the C++ tool's behavior and handles the case where two distinct .winmd files define the same type. The 'CSWINRT2026' or similar pre-existing CI failures the user mentioned across early commits in this branch are explained by this -- the writer has been emitting these duplicates the entire time the C# port was being developed; earlier syntax errors masked them, and the C++ cswinrt.exe invocation in CsWinRTGenerateProjection (now replaced) was deduping them silently via std::map. Wiring the new tool through the projection projects re-exposed the long-standing writer bug. Validation: * dotnet build (writer + ref generator + Native AOT publish): 0 warnings, 0 errors * Targeted repro (passing the cswinrt bin directory which contains both WindowsRuntime.Internal.winmd and cswinrt.winmd): all 5 previously- duplicated interfaces now appear exactly once in the output (was 2x before the fix, matching CI failure). * Full regression check vs ref-truth + impl-truth across all 4 scenarios: - ref SDK: 326/326 files, 31555 throw null; bodies (matches truth) - ref XAML: 27/27 files, 9949 throw null; - impl SDK: 328/328 files, 22 throw null; - impl XAML: 29/29 files, 0 throw null; All baseline counts unchanged.

When the generated file's containing namespace happens to define a 'Windows' sub- namespace (e.g. 'TestComponentCSharp.Windows.*' from the WindowsAppSDK Test projection), C# name lookup resolves the unqualified 'Windows.Foundation.X' to 'TestComponentCSharp.Windows.Foundation.X' first and fails. The C++ cswinrt tool always emits 'typeof(global::...)' for the same reason. We had previously seen this difference in multi-agent validation diffs and labeled it as cosmetic ('mine emits typeof(Windows.X), truth emits typeof(global::Windows.X) - ignore'); turns out it is NOT cosmetic in projection projects whose namespaces shadow the Windows namespace. Fix: always prefix the typeof() argument with 'global::'. Defensively also fall back to 'typeof(object)' when FullName is null/empty (shouldn't happen in WinRT metadata but guards against AsmResolver edge cases).

Root cause: when a runtime class implements an interface (IWarning2) that declares a property as 'get; set;' (because the getter is inherited from a base interface IWarning1), but the actual underlying WinRT method on IWarning2 is only the setter, the writer's explicit-interface-impl emission for the property only emitted 'set { ... }' and skipped the getter entirely. C# requires explicit interface impls to provide every accessor declared on the target interface. Since the C# decl of IWarning2 has both 'get;' and 'set;', the explicit impl must too. C++ cswinrt handles this (code_writers.h:7052-7062) by emitting a synthetic getter that delegates to the base interface where the getter actually lives: get { return ((IBaseInterface)(WindowsRuntimeObject)this).PropName; } Fix: * CodeWriters.Interface.cs: add FindPropertyInterfaceInBases helper that returns the TypeDefinition of the base interface declaring the property (similar to existing FindPropertyInBaseInterfaces, which only returned bool).

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For 'in NonBlittableStruct b' parameters, the writer was emitting 'fixed(int* _b = &b)' followed by passing the int* pointer to a vftbl slot whose ABI signature expects 'NonBlittableStruct*'. This produced CS0266 ('NonBlittable*' to 'int*') and CS1503 ('int*' to 'ABI.NonBlittable*') on every method that takes a non-blittable struct by 'in'. Mirror the C++ tool's is_value_type_in path: when a Ref param is a complex (non-blittable) struct, marshal it through the type's marshaller into a local '__b = MarshallerType.ConvertToUnmanaged(b)', pass '&__b' to the vftbl slot, and dispose '__b' in the finally block — identical to how 'in' (ParamCategory.In) complex struct params are already handled.

The writer was hard-coding 'void**' (2 stars) for the reference-element case, producing parameter signatures that conflicted with the matching ConvertToUnmanaged_'s 'out void** data' parameter and triggering CS1503 'cannot convert from out void* to out void**' errors. The corresponding return-value path (also receive_array) already emits 'void***' correctly via WriteAbiType + '**'; this commit aligns the parameter path with that behavior so the vftbl, Do_Abi signature, and body-side ConvertToUnmanaged calls all use the same pointer level.

The lambda's parameter list and the call to 'TargetDelegate.Invoke(...)' must both forward the delegate's by-reference modifiers (in/out), otherwise CS1676 'Parameter N must be declared with the out keyword' fires (and CS1620 / CS0193 for in/ref). The writer was emitting parameter names without modifiers, e.g. return (a, b) => TargetDelegate.Invoke(a, b); for delegates with 'out long b' / 'in long b' params. Mirror C++ write_parmaeters: emit 'out' for ParamCategory.Out and ReceiveArray, 'in' for ParamCategory.Ref, no modifier otherwise — at both the lambda parameter declaration and the Invoke call site.

As a result, structs whose field types were referenced via TypeRef rows were classified as having unsupported fields, which suppressed emission of the InterfaceEntriesImpl class and the proper Marshaller bodies.

The native delegate's Invoke extension method dispatches a function pointer at vtable slot 3 (Invoke after QI/AddRef/Release), which has the same shape as interface caller dispatch via slot indexing. Replace the bespoke EmitNativeDelegateBody (which only handled the 'simple' case and emitted 'throw null!' for all out/ref/array params) with a call to EmitAbiMethodBodyIfSimple, passing slot=3. Also adopt the same '[MethodImpl(NoInlining)]' + 'unsafe' decoration that interface callers use, and rename the 'objectReference' parameter to 'thisReference' to match the interface convention (purely a name change — no functional difference). Eliminates 29 'throw null!' stubs in TestComponent.cs NativeDelegate extension methods (delegates with 'out T[]', 'in/out T*', complex struct, Generic instance return/param).

AttributeTargets enum value handling: AsmResolver may surface the AttributeUsage validOn parameter as int (the enum's underlying storage type) rather than uint. Accept both, then pass to FormatAttributeTargets which converts the WinMD bitmask values to the System.AttributeTargets enum names. Without this fix, the writer fell through to the int-formatting branch and emitted the raw WinMD value (e.g. 512 for RuntimeClass), which the C# compiler interprets as System.AttributeTargets.Event (4) — wrong. 2.

That check returned false for cross-assembly TypeRefs that we couldn't resolve via the metadata cache (e.g. Microsoft.UI.Composition.ICompositionSupportsSystemBackdrop when the Microsoft.UI.winmd isn't in the input set). The result was 10 Do_Abi methods getting a 'throw null!' fallback in the full WindowsAppSDK regen. WinRT metadata distinguishes value types (encoded as ValueType) from reference types (encoded as Class) at the signature-encoding level. For an unresolved TypeRef whose signature is encoded as Class (i.e. !td.IsValueType), it must be one of class/interface/delegate, since primitives/enums/strings/object/generics are all encoded with their own dedicated element types. Mirrors the C++ abi_marshaler abstraction which dispatches by metadata semantics, not by attempting to resolve the typeref. Added the fallback 'return !td.IsValueType' for unresolved TypeRefs.

Verified across all regen scenarios: throw null! and throw null; counts match exactly before and after this commit. --- .../Writers/CodeWriters.Class.cs | 4 +- .../Writers/CodeWriters.Constructors.cs | 5 +- .../Writers/CodeWriters.RefModeStubs.cs | 47 +++++++++++++++++++ 3 files changed, 50 insertions(+), 6 deletions(-) create mode 100644 src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.RefModeStubs.cs diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Class.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Class.cs index 871273b3d..30d5a150c 100644 --- a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Class.cs +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Class.cs @@ -561,9 +561,7 @@ private static void WriteClassCore(TypeWriter w, TypeDefinition type) } if (!hasRefModeCtors) { - w.Write("\nprivate "); - w.Write(typeName); - w.Write("() { throw null; }\n"); + EmitSyntheticPrivateCtor(w, typeName); } } diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Constructors.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Constructors.cs index 795da1ece..1b42666e9 100644 --- a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Constructors.cs +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Constructors.cs @@ -44,7 +44,7 @@ public static void WriteAttributedTypes(TypeWriter w, TypeDefinition classType) { // Mirrors C++ write_activation_factory_objref_definition (code_writers.h:2748): // in ref mode the activation factory objref getter body is just 'throw null;'. - w.Write("\n{\n get\n {\n throw null;\n }\n}\n"); + EmitRefModeObjRefGetterBody(w); } else { @@ -288,8 +288,7 @@ private static void EmitFactoryCallbackClass(TypeWriter w, MethodSig sig, string // Invoke body is just 'throw null;' (no factory dispatch, no marshalling). if (w.Settings.ReferenceProjection) { - w.Write(" throw null;\n"); - w.Write(" }\n}\n"); + EmitRefModeInvokeBody(w); return; } diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.RefModeStubs.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.RefModeStubs.cs new file mode 100644 index 000000000..ff0414f77 --- /dev/null +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.RefModeStubs.cs @@ -0,0 +1,47 @@ +// Copyright (c) Microsoft Corporation. +// Licensed under the MIT License. + +namespace WindowsRuntime.ProjectionGenerator.Writer; + +/// +/// Reference-projection stub emission helpers.

C++ has no equivalent gates — its abi_marshaler abstraction at code_writers.h:6682 emits a real body unconditionally for every WinRT-valid type. 1) Abi.cs:1436 (EmitDoAbiBodyIfSimple gate) Removed the entire 'allParamsSimple/returnSimple' computation (~70 lines) and its 'throw null!' fallback. Kept the (isAddEvent || isRemoveEvent) check, but converted it from a silent stub emit to a generator-time InvalidOperationException — events have a dedicated EmitDoAbiAddEvent / EmitDoAbiRemoveEvent path upstream and should never reach this function. Also deleted the now-unused IsBlittableStruct helper. 2) Constructors.cs:352 (EmitActivationCtor gate) Removed the 'canEmit' computation (~50 lines) and its 'throw null!' fallback. The body emitter handles every shape we've encountered. 3) WriteAbiType: unresolved cross-assembly value-type encoding When a TypeDefOrRefSignature is encoded as a value type but its TypeRef doesn't resolve via the metadata cache (e.g. WindowId from Microsoft.UI.winmd when that winmd isn't loaded), WriteAbiType used to fall back to 'void*', which produces uncompilable code (struct can't auto-convert to void*). Threaded IsValueType through TypeSemantics.Reference and switched the fallback to emit the projected type name 'global::.' — the consumer's compiler resolves it via their own assembly references. Final state: 0 throw null! across ALL test scenarios: refgen-truth-full : 0 refgen-windows : 0 refgen-pushnot : 0 refgen-everything : 0 (previously 4 — WindowId activator ctors) refgen-everything-with-ui : 0 Bucket B is now fully eliminated. The remaining 'throw null;' (no '!') emissions are all Bucket A ref-mode stubs that mirror C++'s ref-mode behavior exactly. --- .../Metadata/TypeSemantics.cs | 10 +- .../Writers/CodeWriters.Abi.cs | 130 ++++-------------- .../Writers/CodeWriters.Constructors.cs | 50 ------- 3 files changed, 32 insertions(+), 158 deletions(-) diff --git a/src/WinRT.Projection.Generator.Writer/Metadata/TypeSemantics.cs b/src/WinRT.Projection.Generator.Writer/Metadata/TypeSemantics.cs index 2b112e2d1..8cac4af29 100644 --- a/src/WinRT.Projection.Generator.Writer/Metadata/TypeSemantics.cs +++ b/src/WinRT.Projection.Generator.Writer/Metadata/TypeSemantics.cs @@ -45,7 +45,7 @@ public sealed record GenericInstanceRef(ITypeDefOrRef GenericType, List @@ -63,14 +63,14 @@ public static TypeSemantics Get(TypeSignature signature) GenericParameterSignature gp => gp.ParameterType == GenericParameterType.Type ? new TypeSemantics.GenericTypeIndex(gp.Index) : new TypeSemantics.GenericMethodIndex(gp.Index), - TypeDefOrRefSignature tdorref => GetFromTypeDefOrRef(tdorref.Type), + TypeDefOrRefSignature tdorref => GetFromTypeDefOrRef(tdorref.Type, tdorref.IsValueType), SzArrayTypeSignature sz => Get(sz.BaseType), // SZ arrays handled by callers ByReferenceTypeSignature br => Get(br.BaseType), _ => GetFromTypeDefOrRef(signature.GetUnderlyingTypeDefOrRef() ?? throw new System.InvalidOperationException("Unsupported signature: " + signature?.ToString())), }; } - public static TypeSemantics GetFromTypeDefOrRef(ITypeDefOrRef type) + public static TypeSemantics GetFromTypeDefOrRef(ITypeDefOrRef type, bool isValueType = false) { if (type is TypeDefinition def) { @@ -83,13 +83,13 @@ public static TypeSemantics GetFromTypeDefOrRef(ITypeDefOrRef type) if (ns == "System" && name == "Guid") { return new TypeSemantics.Guid_(); } if (ns == "System" && name == "Object") { return new TypeSemantics.Object_(); } if (ns == "System" && name == "Type") { return new TypeSemantics.Type_(); } - return new TypeSemantics.Reference(reference); + return new TypeSemantics.Reference(reference, isValueType); } if (type is TypeSpecification spec && spec.Signature is GenericInstanceTypeSignature gi) { return GetGenericInstance(gi); } - return new TypeSemantics.Reference((TypeReference)type); + return new TypeSemantics.Reference((TypeReference)type, isValueType); } private static TypeSemantics GetCorLib(ElementType elementType) diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs index 1caa3f191..6954efd47 100644 --- a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs @@ -1328,99 +1328,26 @@ private static void EmitDoAbiRemoveEvent(TypeWriter w, EventDefinition evt, Meth } /// - /// Emits a real Do_Abi (CCW) body for the cases we can handle, else throw null!. + /// Emits a real Do_Abi (CCW) body for the cases we can handle.

Our CCW Do_Abi (server-side) was treating them like 'out T' / 'ref T' (mutable by-ref): - Zeroed * before the call (destroying the input) - Declared a default-initialized local '__' - Passed 'ref __' to the projected delegate/method (default value!) - Wrote back '* = ConvertToUnmanaged(__)' after the call This silently corrupted any 'in T' parameter on a CCW boundary. The TestComponent test 'Param14Call' calls a delegate as 'handler(a, a, b)' where the second arg is the 'in const&' b parameter.

The interfaces are needed at runtime to construct the BCL types from native (e.g. the marshalling pipeline calls INotifyCollectionChangedEventArgsFactory.CreateInstanceWithAllParameters to build a System.Collections.Specialized.NotifyCollectionChangedEventArgs from the native fields).

charset=UTF-8 Content-Transfer-Encoding: 8bit The newly-emitted INotifyCollectionChangedEventArgsMethods.Action ABI helper (re-introduced by removing SuppressExclusiveInterfaces) referenced 'global::Windows.UI.Xaml.Interop.NotifyCollectionChangedAction' as the ABI type for the local '__retval' and the function pointer signature, but that type doesn't exist in the .NET projection — it's a mapped type that lives at 'System.Collections.Specialized.NotifyCollectionChangedAction'. The generated source therefore failed to compile (CS0234, CS1503). The bug was in GetProjectedEnumName in CodeWriters.Abi.cs which read the raw namespace+name from the TypeDefinition without applying the MappedTypes translation that WriteTypedefName normally does. Apply the same MappedTypes lookup so the projected name gets used end-to-end (return type, local declaration, function pointer signature, and return statement — no spurious cast needed since the local is already the projected type). Verified with WinSDK + WinUI aligned regen: 0 occurrences of the unmapped 'Windows.UI.Xaml.Interop.NotifyCollectionChangedAction' / corresponding 'Microsoft.UI.Xaml.Interop.NotifyCollectionChangedAction' anywhere in the generated output (matches truth's 0 occurrences). Validation: - AuthoringTest IIDs: 92/92 still match (no regression) - All 5 standard regen scenarios: 0 throw null! - Truth diff on Windows.UI.Xaml.Interop.cs: only stylistic diffs remain (objectReference→thisReference, inline delegate* vs Vftbl, collection expression syntax, namespace qualification) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../Writers/CodeWriters.Abi.cs | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs index aea063015..ba942294c 100644 --- a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs @@ -5939,6 +5939,16 @@ private static string GetProjectedEnumName(TypeDefinition def) { string ns = def.Namespace?.Value ?? string.Empty; string name = def.Name?.Value ?? string.Empty; + // Apply mapped-type translation so consumers see the projected (.NET) enum name + // (e.g. Windows.UI.Xaml.Interop.NotifyCollectionChangedAction → + // System.Collections.Specialized.NotifyCollectionChangedAction).

The class members on Simple (Method2, InvokeEvent0, etc.) all dispatch through ISimple's vtable using slot indices that include the merged contributions of ISimple2-9, IOrange, IBanana etc. There is NO separate vtable for ISimple5 on the COM object. Before this commit, our generator was emitting: - A separate _objRef_test_component_fast_ISimple5 field (and lazy QI) - A separate ISimple5Methods static class - Class member dispatch through ISimple5Methods.Method2(_objRef..ISimple5) QI for ISimple5 either failed or returned an unrelated vtable, so the call to slot 6 of "ISimple5" produced 0xC0000005 access violations at runtime (visible in CI as Fatal error 0xC0000005 in ABI.test_component_fast.ISimple5Methods.Method2 from test_component_fast.Simple.Method2 in UnitTest.TestWinRT.Fast_Abi_Simple). This commit ports the C++ FastAbi handling to match cswinrt.exe exactly: 1. WriteClassObjRefDefinitions (CodeWriters.ObjRefs.cs): skip emitting _objRef_* fields for fast-abi non-default exclusive interfaces. Mirrors C++ code_writers.h:2960 (write_class_objrefs_definition). 2. WriteInterfaceMarshallerStub (CodeWriters.Abi.cs): - Skip Methods class for fast-abi non-default exclusive interfaces. Mirrors C++ code_writers.h:9082-9089 (early return on contains_other_interface). - For the default interface of a fast-abi class, emit a merged Methods class containing the default interface's members AT slot 6+ followed by each [ExclusiveTo] non-default interface's members at progressively increasing slot indices. Slot index advancement uses CountMethods(default) + GetClassHierarchyIndex(class) for the first other interface, then adds CountMethods(other) per next interface. Mirrors C++ code_writers.h:9113-9128. - Refactored the existing per-interface emission body into the EmitMethodsClassMembersFor helper for reuse. 3. WriteInterfaceMembers (CodeWriters.ClassMembers.cs): when a fast-abi class member's interface is exclusive_to that class, redirect the ABI Methods static class name AND the _objRef_ field to the default interface. Mirrors C++ code_writers.h:4250-4251 (semantics_for_abi_call assignment). New helpers in CodeWriters.Class.cs: - FindFastAbiClassType(iface): returns the [ExclusiveTo] class if it's fast-abi (mirrors C++ find_fast_abi_class_type). - GetFastAbiClassForInterface(iface): returns (class, default, others) if iface is exclusive_to a fast-abi class (mirrors C++ get_fast_abi_class_for_interface). - IsFastAbiOtherInterface(iface): true if iface is in a fast-abi class's other_interfaces list. - IsFastAbiDefaultInterface(iface): true if iface is the default of a fast-abi class. In CodeWriters.Abi.cs: - GetClassHierarchyIndex(class): mirrors C++ get_class_hierarchy_index in helpers.h:1496. - CountMethods(iface), HasEmittableMembers, InterfacesEqualByName. Validated against test_component_fast (the affected scenario): - ISimpleMethods now has all merged members at correct slots (6,7,8,9, 10,11,12,13,16,17,18,...) matching truth byte-for-byte - ISimple5Methods refs in generated output: 0 (was N before, matched truth) - _objRef_test_component_fast_ISimple5: 0 (was 1 before, matched truth) - Class Simple methods all dispatch through ISimpleMethods + _objRef_test_component_fast_ISimple (matches truth exactly) Validated regression-free against: - All 5 standard regen scenarios: 0 throw null! - AuthoringTest aligned: 92/92 IIDs match (no regression) - WinUI aligned (with test_component winmds available): missing=0 extra=0 diff=0 (was 4 missing before this fix) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- .../Writers/CodeWriters.Abi.cs | 113 +++++++++++++++--- .../Writers/CodeWriters.Class.cs | 68 +++++++++++ .../Writers/CodeWriters.ClassMembers.cs | 23 +++- .../Writers/CodeWriters.ObjRefs.cs | 22 ++++ 4 files changed, 209 insertions(+), 17 deletions(-) diff --git a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs index ba942294c..28c420d5b 100644 --- a/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs +++ b/src/WinRT.Projection.Generator.Writer/Writers/CodeWriters.Abi.cs @@ -3577,6 +3577,12 @@ private static void WriteInterfaceMarshallerStub(TypeWriter w, TypeDefinition ty bool useInternal = (TypeCategorization.IsExclusiveTo(type) && !w.Settings.PublicExclusiveTo) || TypeCategorization.IsProjectionInternal(type); + // Fast ABI: if this interface is a non-default exclusive-to interface of a fast-abi + // class, skip emitting it entirely — its members are merged into the default + // interface's Methods class.

At runtime the merged native vtable exposes only the default interface's vtable; the secondary interface's slot index is therefore invalid and AddRef/Release on the resulting EventSource walks a bogus pointer, producing 0xC0000005 in the unit test 'TestWinRT.Fast_Abi_Simple' at 'Simple.add_Event0'. C++ truth (code_writers.h:4293) gates the inline path on '!is_fast_abi_iface || is_default_interface'. When false (i.e. fast-abi exclusive non-default), it dispatches through the merged ABI Methods class helper instead, which uses the correct merged-vtable slot and a ConditionalWeakTable for per-instance event-source caching: add => global::ABI..Methods.( (WindowsRuntimeObject)this, _objRef_<...>).Subscribe(value); remove => ... .Unsubscribe(value); WriteInterfaceMembers already had this ABI-class rerouting for methods and properties (commit ee6aa4c7); extend the same rerouting to events. Validation: regenerated all 8 standard scenarios; the 'event Event0' block in 'Simple' now matches truth byte-for-byte; non-fast-abi events still emit the inline _eventSource_ field pattern (refgen-windows still has 4074 _eventSource_ refs); AuthoringTest IIDs preserved at 92/92.

'' flows the consuming project's Platform to the reference, so when a projection was built for 'Platform=x86', MSBuild tried to build the ref generator csproj at 'PlatformTarget=x86'. The ref generator has 'PublishAot=true', which auto-resolves 'RuntimeIdentifier=win-x64' (the host RID), and the SDK rejects the combination with NETSDK1032: error NETSDK1032: The RuntimeIdentifier platform 'win-x64' and the PlatformTarget 'x86' must be compatible. [src\\WinRT.Projection.Ref.Generator\\WinRT.Projection.Ref.Generator.csproj] Mirror the existing pattern used for the other NAOT-published generators ('WinRT.Projection.Generator', 'WinRT.Interop.Generator', 'WinRT.Impl.Generator'): declare a '' on the ref generator inside 'src/cswinrt.slnx' for each of the eight 'Projections/*/...csproj' entries. Solution-level BuildDependency does not flow Platform/PlatformTarget into the dependency, so the ref generator builds at its own default 'AnyCPU' platform regardless of which projection-project platform is being built. Removed 'src/Projections/Directory.Build.targets' entirely (its only purpose was the now-removed ProjectReference; MSBuild walks up to the parent 'src/Directory.Build.targets' automatically).

The writer only ingests `.winmd` files (verified by `MetadataCache.Load` and `ProjectionWriterOptions.InputPaths` usage), so the branch never fires. The C++ tool's equivalent `write_type_inheritance` (code_writers.h:7395) also only checks for `object_type` (System.Object) -- there is no `WindowsRuntimeObject` check. The check in our C# port was added speculatively/defensively during early porting. Replaces the two-condition `isObject` check with a direct `!(baseNs == "System" && baseName == "Object")`, matching C++ behavior. Validation: regenerated all 8 standard scenarios (full, windows, everything, everything-with-ui, pushnot, authoring-aligned, winsdk-aligned, winui-fast) -- all byte-identical to the pre-change baseline (SHA256 of every emitted `.cs` unchanged). The branch was indeed unreachable for the entire WinSDK + WinUI + test_component projection corpus (1,500+ runtime classes). Addresses PR #2415 review comment r3205242890.

The attribute's constructor signature is ComposableAttribute(Type factoryInterface, CompositionType visibility, uint version, ...) so the visibility enum (marshalled as `int` in the custom-attribute blob) is always at fixed-argument index 1. The previous loop-based "find the first `int`-typed arg" implementation was unnecessarily general and obscured the intent (and the doc comment already specifically said "for `[ComposableAttribute]`"). Replace with a list-pattern that matches index 1 directly: if (attr.Signature is { FixedArguments: [_, { Element: int e }, ..] }) { return e; } return 0; Validation: regenerated all 8 standard scenarios (full, windows, everything, everything-with-ui, pushnot, authoring-aligned, winsdk-aligned, winui-fast) -- all byte-identical to the pre-change baseline. Confirms the visibility is in fact at index 1 across the full WinSDK + WinUI + test_component corpus (would have shifted `protected`/`public` composable factories otherwise).
