dnSpy v6.6.1 Release Candidate 1 14-05-2026

New features:

Added a new String References tool window, which allows viewing all strings present in the .NET metadata and method bodies (thanks to @Washi1337).
Added a new .NET 10 distribution (dnSpy-net), which is not self-contained and contains both x64 and x86 binaries. This is intended as a more modern alternative to the dnSpy-netframework distribution. This is the recommended distribution if you have .NET 10 already installed on your system.

dnSpy now detects when it is being run under Wine on Linux and disables WPF hardware acceleration to improve compatibility.
SDK style projects can now be exported from dnSpy.Console.
dnSpy's XML syntax highlighter now properly supports CDATA.
Added support for the AllowByRefLike metadata flag on generic parameters in edit dialogs.
Added support for generating .slnx solution files when exporting the decompilation to a project file.

Improvements and bug fixes:

Updated from .NET 8 to .NET 10.
Ensure the Save Module window appears for at least some time on screen to signal that the module was actually written.
Fixed the decompilation of the calling convention field of DllImport for .NET.
Fixed export of resources with MemoryStream type when generating RESX files.
Added additional monospace fallback fonts to improve compatibility for running dnSpy under Wine.
Fixed incorrect thread exit codes being displayed in the debugger Output dialog.
Improved UI tooltips for metadata members with partially corrupted metadata.
Added more safeguards against StackOverflowException in the decompiler.
Fixed a rare decompiler crash relating to the C# fixed statement.
Properly escape resource names in the treeview.

Improved exporting BAML files to project files.

Fixed incorrect syntax in IL disassembler and improved accuracy.
Truncate the content of the long string resources when displaying them.
