`QueryGeneratorTestUtil.GenerateCompileAndAssert` internally uses
`Microsoft.CodeAnalysis.CSharp.CSharpCompilation.Create()` and `Microsoft.CodeAnalysis.MSBuild.MSBuildWorkspace.Create()`. I get an interactive, debuggable source generator development environment this way.
Same as you, initially I used "comments as debugging" hacks but above way is way more efficient.
