VS2022 Add-in. Click on any method or class to see JIT's codegen and more.
Starting with .NET 7.0 RC1 this add-in no longer requires a local build of dotnet/runtime repo. However, it offers more features with a local one, to obtain a local one please follow these steps:
git clone git@github.com:dotnet/runtime.git
cd runtime
build.cmd Clr+Clr.Aot+Libs -c Release -rc Checked
# optional (for crossgen2 + arm64 for hw intrinsics):
build.cmd Clr.CoreLib -c Release -a arm64See RELEASE_NOTES.md
Click on Extensions\Manage Extensions menu, select Online tab and type Disasmo in the "Search"
text box. Once the add-in is installed you have to close all active instances of VS2022
to let the installer finish its job.
- Hot-key to quickly see codegen (Alt+Shift+D by default, can be changed in VS's settings)
- Is able to show codegen for ARM64
- Flowgraphs and JitDumps for JIT contributors
- Diffs
- "System.Runtime.Intrinsics quick search" tab
- Inliner's decisions
- 'Run' mode. Is useful for e.g. PGO inspection
- Only .NET 6.0 and later projects are supported with custom runtime
- .NET 7.0 RC1 (or newer) is needed for non-custom runtime mode
- I only tested it for simple Console Apps, but it should work for libs as well
- Generic methods are only supported in 'Run' mode
- Resharper hides Roslyn actions by default (Uncheck "Do not show Visual Studio Light Bulb").
- The lightbulb can be slow on first launch
- MvvmLight (MIT)
- AvalonEdit (MIT)
