Extension Everything Under the Covers by the ILSpy maintainers - .NET Stammtisch Linz

YouTube
Interestingly enough, #dotpeek gives more accurate decompiled C# code than #ilspy - the top if statement actually does a return on equality, it doesn't check for inequality.
There will be an in-person user group meetup on ILSpy end of February that is also streamed (recorded) with extension everything deconstructed plus #ILSpy engineering challenges & changes (delta July 22 - now).
The imminent preview 2 of #ILSpy 10 will come with one feature removed: translations. For reasons see https://github.com/icsharpcode/ILSpy/pull/3647#issuecomment-3696133844, for future plans https://github.com/icsharpcode/ILSpy/pull/3648#issue-3767273716
Open VSX Registry

VS 2026 Insiders comes with #ILSpy v9.1 (#VisualStudio 17.14 ships with 8.2)
#dotnet published .wasm files are now support in #ILSpy #vscode with v0.22 https://github.com/icsharpcode/ilspy-vscode/releases/tag/v0.22.0, other popular format (nupkg) incoming https://github.com/icsharpcode/ilspy-vscode/issues/569. Moving xplat stuff to ILSpyX is paying off.
