v6.5.0

New features:

• dnSpy now runs on .NET 8 and .NET Framework 4.8.
• dnSpy now handles TypeRef rows with a ResolutionScope of 0 in the same way as the CLR rather than following the ECMA specification.
• The low-level metadata editor is now aware of the implications of the #JTD metadata stream being present.
• Enable Windows targetting in project files to allow compiling on other platforms (Note: dnSpy will still only run on Windows due to the WPF dependency)
• Added binding redirects for various common assemblies with frequent version bumps to make extensions compiled for older versions load more seamlessly.
• Added support for new resource serialization formats added as part of System.Resources.Extensions
• Added a new, opt-out, update checker which runs on startup and will display an update notification in a new information bar component.
• C# Interactive now references additional libraries giving access to newer features like Span<T> or immutable collections.
• Enabled Server and concurrent GC as well as RDP hardware acceleration in the .NET 8 builds
• ILSpy Decompiler:
  • Added support for C# ref types to the decompiler - ref types are now correctly decompiled into the proper C# syntax instead of being decompiled into pointer types.
  • Added support for C# function pointers to the decompiler - Function pointers are now correctly represented using the C# syntax rather than simple types of name method
• Debugger
  • The debugger now supports displaying tuple element names, dynamic types, and native integer types defined in custom attributes.
  • The debugger expression evaluator now includes support for tuple element names and dynamic types.
  • Debugger tool windows now use the correct C# 9 function pointer syntax as well as the correct ref type syntax.
  • Display a message dialog when valid metadata cannot be obtained when executing the Open module from memory command.
  • Added an additional option to the .NET Framework start debugging dialog to override the CLR version to use for debugging purposes. This can be helpful for files that use obfuscated native loaders when dnSpy can't automatically detect the correct CLR version.

Improvements and bug fixes:

• Fixed loading XML documentation for System.Private.CoreLib.dll.
• Improve the method overridden by analyzer to take into account explicit overrides in the metadata.
• Minor improvements to the low-level metadata table editor.
• Improve dependency assembly resolution for cases where .NET Core/.NET 5+ or .NET Framework 2.0 might not be installed.
• Improve performance of members overridden by analyzers.
• Prevent the dependency assembly resolver from performing IO calls on assembly references with invalid file names.
• Minor improvements to the member analyzer to reduce false positives.
• Fixed some null reference errors that could occur when deleting a member or type that was still referenced in a module.
• Improve assembly resolution performance when the module list is frozen (this is a backend change, no behavioral changes will be observable)
• Updated Chinese translations.
• Debugger:
  • Fixed some cases where expressions generated for the expression evaluator were missing parenthesis leading to errors.
  • Improve formatting of multi-dimensional array types in the local, watch, and autos windows.
  • Extend the breakpoint filter expression evaluator to allow for more complicated expressions.
  • Fixed a bug that caused the Raw Locals view to fail when the assembly referenced multiple core libraries.
  • Improve handling of dynamic types in Raw Locals display mode.
  • Extend support for attaching to Unity processes (by @rigdern)
  • Gracefully handle the case when the CorDebug IMetaDataImport interface cannot be obtained for a given module.
  • Improve the accuracy of the Break on entry point and break on module constructor feature for single file bundle debugging.
• ILSpy Decompiler:
  • Usual round of optimizations and performance improvements.
  • Fixed incorrect methodof decompilation for ldtoken of a method.
  • Corrected expected prefixes on call and ldftn instructions.
  • Improve ambiguous type name analysis to include namespace names as ambiguous identifiers.

Thanks to everyone for reporting issues, opening pull requests, and supporting the project through other means! This release would not have been possible otherwise :P A special thanks goes out to all my current and past GitHub Sponsors for supporting this project!

v6.3.0

dnSpyEx 6.3.0 brings many improvements to the already existing components in dnSpy as well as features an improved search component. Many bugs and issues caused by obfuscated or malformed binaries have been fixed. The debugger received quite a lot of improvements for both the CorDebug and Mono APIs to improve the debugging experience. The decompiler has also received quite a few changes to help fix crashes and incorrect decompiled code. This update is recommended for all users of dnSpy and dnSpyEx!

New features:

• Improved Search tool window
  • Display member types in search results (return types, parameter types, etc.) to make it easier to locate the right member.
  • Tooltips on search results now contain more information, including full member signatures. If the result is located in a method body, the appropriate instruction is also included in the tooltip.
  • Literal and enum fields are now included in search results when searching for a constant.
  • Improved analysis of custom attributes. Previously arrays in custom attributes or boxed custom attributes were not searched, now they are.
  • Added an option to disable searching compiler-generated members.
  • Added support for searching DateTime resources when searching for constants.
  • Reduced heap allocations that occurred during the search process.
  • Include properties with literal constants in search results when searching for constants.

  • Add support for GetObjectValueAtAddress Roslyn expression compiler intrinsic. It is now possible to enter expressions like @0x12345678 to retrieve an object at a specific memory address. Due to debugger API limitations, this is only available when utilizing the CorDebug API (.NET Framework, .NET Core, .NET 5/6/7/etc.)
  • CorDebug:
    • Add support for Just My Code debugging including an option to disable stepping into system modules and an option to avoid stepping into code outside the primary module.

  • Improve debug info generation for inlined finally methods in yield return state machines.
  • Improve performance and reduced heap allocations in the decompiler and IL disassembler.
  • Extended type analysis for switch, throw, and ckfinite OpCodes.
  • Fixed a crash that occurred when the HandlerStart property of an exception handler was null (by @mobile46).
  • Fixed setting incorrect brace annotations for switch case blocks.
  • Extended support for methods utilizing the __arglist parameter.
  • Improved jump-to-reference navigation in the IL disassembler.

  • Fix a potential exception when searching a dynamic module (by @mitchcapper).
  • Improved debugger evaluation correctness and accuracy.
  • Fix timing issues in debugger thread dispatchers.
  • Display a warning message when detaching the debugger will lead to process termination.
  • Fix Locals windows failing to display locals when debugging a module with an invalid MVID.
  • Child nodes should not be displayed for values of types IntPtr and UIntPtr.
  • Fix the architecture incompatibility warning for files targeting .NET Framework 1.x but being executed on CLR version 2.
  • CorDebug:
    • Improve suppression of NGEN image loading leading to a better debugging experience for modules present in the GAC.
    • Introduce a workaround for a .NET 6.0 bug that occurred when a debugger was attached to a process that utilized dynamic modules. (by @josegomez)
    • Use the CorDebug API directly to read thread and exception information to avoid issues with certain anti-dumping techniques.
    • Improve debugging support for legacy .NET Framework versions.
  • Mono/Unity:
    • Improved dynamic module detection and metadata fetching for newer Mono debugger API versions.
    • Fix computation of OffsetToStringData value resulting in improved evaluation accuracy and fixed Show in Memory command result.
    • Improved and optimized computation of OffsetToArrayData, it should now work smoother on newer Mono debugger API versions.
    • Use MDToken-based resolution for types and methods when possible on newer Mono debugger API versions.
    • Improve the result of the Show in Memory command for objects on newer Mono debugger API versions.
• BAML decompiler:
  • Improved analysis of BAML connection IDs.
  • Fixed incorrect decompilation of readonly properties in XAML code.
  • Fixed a crash resulting from unescaped member identifiers.
