Keep each outbound call's generic result type alive until completion so result deserialization no longer reconstructs it from runtime Type values. Behavior: preserved State: builds; parity coverage follows in the next commit Review hint: the pending-call abstraction replaces TaskCompletionSource reflection without changing completion, cancellation, or failure flow.

Exercise typed completion for nullable outbound JS results in addition to the existing object, array, failure, and cancellation coverage. Behavior: preserved State: complete for typed pending-call completion Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Move method scanning, argument parsing, invocation, async adaptation, and caches behind an internal reflection resolver so DotNetDispatcher only coordinates wire dispatch. Behavior: preserved State: builds; generated resolution follows in the next commit Review hint: the resolver contains the legacy reflection implementation and its suppressions; DotNetDispatcher now handles only protocol flow.

Expose executable JS-invokable descriptors and compose generated lookup ahead of an independently switchable reflection compatibility resolver. Behavior: changed: runtimes can supply generated JS-invokable descriptors that take precedence over reflection State: builds; dispatch matrix coverage follows in the next commit Review hint: SourceGeneratedJSInvokableMethodResolver defines precedence and inheritance; the factory keeps reflection enabled by default behind its own linker-recognized switch. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Cover manual generated descriptors, generated-first precedence, inheritance and alias rules, misses, reflection parity, async completion, and object-reference disposal. Behavior: preserved State: complete for runtime descriptor resolution Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Add the JS-only metadata generator foundation, extend the experimental application context with JSInvokableMethods, and let RemoteJSRuntime flatten registered contexts into generated-first dispatch. Behavior: changed: registered application metadata contexts now contribute generated JS-invokable methods State: builds; generator and runtime integration tests follow in the next commit Review hint: this layer emits only JsonTypeInfoResolver and JSInvokableMethods; component and bindable collection/emission are intentionally absent. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Exercise generated JS descriptors across method shapes, aliases, inheritance, and serialization, and verify registered contexts reach RemoteJSRuntime in registration order. Behavior: preserved State: complete for application-generated JS metadata Review hint: the generator test project contains only the JS slice; component and bindable generator suites remain deferred. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Discover the Web assembly's built-in JS callback provider, spread its descriptors through generated contexts via UnsafeAccessor, and add callback-specific BrowserFile contracts only to the owning Web build. Behavior: changed: generated application contexts now include framework-owned Web callbacks State: builds; provider coverage follows in the next commit Review hint: the generator only knows the provider assembly and factory shape; callback signatures and JSON contracts remain owned by Components.Web. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Verify generated contexts reach the Components.Web callback provider through the emitted UnsafeAccessor and include the complete built-in callback descriptor set. Behavior: preserved State: complete for framework callback metadata Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Delete the task-result generic reconstruction helper and broad linker warning XML now that pending calls retain result types and reflection suppressions sit beside the exact legacy operations. Behavior: preserved State: complete Review hint: both deleted artifacts have no remaining callers or live suppression targets. Co-authored-by: Copilot App <223556219+Copilot@users.noreply.github.com>
Prove the owning Components.Web serializer context emits BrowserFile and BrowserFile[] metadata and that the built-in NotifyChange descriptor consumes the array contract. Behavior: preserved State: complete Review hint: this test guards the Web-only side of the existing COMPONENTS_WEBASSEMBLY conditional.

RemoteJSRuntimeBrowserFileandBrowserFile[]callback contracts while the shared WebAssembly build excludes inaccessible internal typesReview focus
Please review only the JSInterop runtime, generated dispatch metadata, and framework-owned JS callback provider in this layer. Component/bindable metadata, component runtime/discovery, framework component providers, and strict Native AOT proof are intentionally deferred to later stack layers.
