C# Source Generators

A list of C# Source Generators (not necessarily awesome), because I haven't found a good list yet.

C# Source Generators is a Roslyn compiler feature introduced in C#9/.NET 5. It lets C# developers inspect user code and generate new C# source files that can be added to a compilation.

Add GitHub topic csharp-sourcegenerator to your generator repo - let's get it started!

Documentation and samples

Source Generators

TIL to debug a source generator in VS 16.10: upgrade Microsoft.CodeAnalysis.CSharp to 3.10.*, add <IsRoslynComponent>true</IsRoslynComponent> to source generator project, select Roslyn Component for Launch in Project Properties Debug page, choose Target then F5 🚀

See files emitted by #SourceGenerators by adding these properties to your (*.csproj) project file:

<EmitCompilerGeneratedFiles>true</EmitCompilerGeneratedFiles>
<CompilerGeneratedFilesOutputPath>$(BaseIntermediateOutputPath)Generated</CompilerGeneratedFilesOutputPath>

I made a thing: https://github.com/chsienki/Kittitas

If you're building Roslyn Source Generators or Analyzers check it out, it makes debugging them inside the compiler easier. #roslyn #csharp #dotnetcore #sourcegenerators #analyzers

Build failed in WPF projects microsoft/CsWin32#7:

If your build failed in a _wpftmp.csproj file you need to add following property to your (.csproj) project file:

<IncludePackageReferencesDuringMarkupCompilation>true</IncludePackageReferencesDuringMarkupCompilation>

and use at least .NET 5.0.102 SDK

Reference local projects or embed NuGet packages to source generator assemblies dotnet/roslyn#47517:

⚠ Please be aware that this may result in crashes, when another generator or SDK component loads such an assembly with lower version. If you can, please avoid embedding additional DLLs/packages.

You can add a dependency to a source generator in the same solution through three steps:

  1. Add a <PackageReference>, making sure to set both GeneratePathProperty="true" and PrivateAssets="all"
  2. Add a build target to add <TargetPathWithTargetPlatformMoniker> elements as part of GetTargetPath, and add all the required dependency assemblies inside this target, making sure to set IncludeRuntimeDependency="false"
  3. Update <GetTargetPathDependsOn> to ensure the target from the previous step is used

You can see an example of these steps here: https://github.com/dotnet/roslyn-sdk/blob/0313c80ed950ac4f4eef11bb2e1c6d1009b328c4/samples/CSharp/SourceGenerators/SourceGeneratorSamples/SourceGeneratorSamples.csproj#L13-L30
