#ilspy — Public Fediverse posts

These days it almost seems as if LLMs are #ILSpy's biggest "customer" - total user downloads ~9.5k vs ilspycmd ~ 12k (six day period since release of v10.0)

The recording of last week's talk "Extension Everything Under the Covers" is now available https://www.youtube.com/watch?v=nP3JEbPWgEc. Slides can be found at https://github.com/christophwille/demosatconferences/blob/master/ILSpy_Meetup_Linz_Feb26_ExtensionEverything.pdf And in case you first want to watch the previous talk, please go to https://youtu.be/rexge_m4JR0?t=1186 #dotnet #csharp #ILSpy

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

Now on Open VSX as well https://open-vsx.org/extension/icsharpcode/ilspy-vscode #ILSpy

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.

Merged initial #ILSpy decompiler support for #csharp 14 extension members on #dotnet 10 (limitations see https://github.com/icsharpcode/ILSpy/pull/3530)

2025 #ILSpy dev days in review https://github.com/icsharpcode/ILSpy/issues/3420#issuecomment-3149252686

Extension everything #dotnet current state of affairs in #ILSpy 10

And now extension starts with unit tests inside #ILSpy

Our #ILSpy DevDays start off by comparing https://github.com/dotnet/csharpstandard/blob/draft-v9/standard/conversions.md to standard-v5

Our first preview of #ILSpy 10.0 is now officially available at https://github.com/icsharpcode/ILSpy/releases/tag/v10.0-preview1 including API diff (see the PR description for how-to use)

Export as JSON is included in the #ILSpy API diff feature, and using CoPilot, you can actually turn that into a nice markdown report

Coming soon to #ILSpy 10 - API diff

#ILSpy master is now #dotnet 10.0 as of https://github.com/icsharpcode/ILSpy/commit/29e5e7df213a6c53bf77243f8c52592a2962c90b

If anyone happens to be in Vienna Aug 1st-3rd and wants to chat #ILSpy in person, feel free to get in touch https://github.com/icsharpcode/ILSpy/issues/3420

Time to #Roslyn for #ILSpy 9.1 - three (!) days https://github.com/dotnet/roslyn/pull/78270

We are approaching the ten year mark of publishing our #ILSpy decompiler package on https://www.nuget.org/packages/ICSharpCode.Decompiler/#versions-body-tab - 2.3.0 was the first one released on April 26th, 2015

Our #ILSpy NuGet packages Decompiler, BamlDecompiler and ILSpyX now contain SBOMs courtesy of https://github.com/microsoft/sbom-tool/tree/main/src/Microsoft.Sbom.Targets (just landed in master)

You might have seen a few commits recently that had nothing to do with #ILSpy per se - but with improving our OpenSSF score card (least privilege for workflow tokens, security.md, actually putting LICENSE where it always was supposed to be...) - and it paid off! We went up to seven (from a not all-too-shabby 5.3).

Just merged - creating Mermaid diagrams via #ILSpy #dotnet tool. Docs at https://github.com/icsharpcode/ILSpy/wiki/Diagramming, sample at https://ilspy.net/ICSharpCode.Decompiler/diagrammer/index.html?t=IEntity-IEvent-IField-IMember-IMethod-IModule-INamedElement-INamespace-IParameter-IProperty-ISymbol-IVariable&d=LR&i=tim (not on nuget.org, you need to grab build artefacts). Thanks fly out to Holger Schmidt https://github.com/h0lg/netAmermaid

We are getting close to releasing Preview 3 of #ILSpy 9. Please grab the latest bits https://github.com/icsharpcode/ILSpy/actions/workflows/build-ilspy.yml?query=branch%3Amaster and give it a spin!

Want to meet #ILSpy team members? @siegfriedpammer and @willechristoph will be heading to Update Conference in Prague in November.

In a week, the #ILSpy team is meeting in Vienna for their yearly dev meeting https://github.com/icsharpcode/ILSpy/issues/2943 - one discussion topic will be "Is supporting #dotnet #trimming and/or #aot a thing for our decompilation engine?" Any use cases you can think of? (most of the users we know of don't need it)

If you have some time on your hands, please grab latest #ILSpy bits from https://github.com/icsharpcode/ILSpy/actions/workflows/build-ilspy.yml?query=branch%3Amaster (> .7780) and give the big (internal) WPF changes in ILSpy a thorough test drive - no changes in UI behavior should have slipped through, otherwise please file a bug report! (for reference: https://github.com/icsharpcode/ILSpy/issues/3284)

C# 12 primary constructors are merged for #ILSpy 9.0 https://github.com/icsharpcode/ILSpy/pull/3235

Been using a SnapDragon X laptop during the #ILSpy developer days - except for the Bluetooth issue with an external audio device and the already-known (and expected) performance issues with our unit tests, it was a good experience (uneventful).

The 2024 edition of the #ILSpy developer days is a wrap, and all team members are on their ways home. Safe travels!

Over at the @avaloniaui blog, they published the first public beta release of the XPF version of
#ILSpy for Mac https://avaloniaui.net/blog/ilspy-for-macos-first-public-beta-release
