How can I look at the generated code ?

[Kulgann]

Or rather how can I tell that code generation is being used instead of reflection ? Also which dll should be included in the Unity project SourceGenerator or SourceGenerator.Roslyn3

How to see the generated code (and check it’s used instead of reflection)

• In Rider / Visual Studio: open your Unity solution and look under
  YourProject → Analyzers → VContainer.SourceGenerator → Generated files.
  You can Go to Declaration from usages to jump into the generated source.
  (Unity sometimes refreshes this view after a full recompile.)
• Recognize VContainer’s generated types: you’ll see nested classes like
  __GeneratedInjector on your injectable types. A quick runtime sanity check:

// Put a class name that should be targeted by SG
var t = typeof(MyInjectable).GetNestedType("__GeneratedInjector",
    System.Reflection.BindingFlags.NonPublic);
Debug.Log(t != null ? "VContainer SG is active" : "Fallback to reflection");

• Stack traces during container build/resolve will also contain
  __GeneratedInjector when SG is active.

Which DLL to include?

• Prefer VContainer.SourceGenerator.dll.
• If you hit a Roslyn version mismatch (Unity console complaining about
  Microsoft.CodeAnalysis 3.x), switch to VContainer.SourceGenerator.Roslyn3.dll.

Unity setup (per VContainer docs)

1. Drop the chosen DLL under Assets/.
2. Select it and add the Asset Label: RoslynAnalyzer.
3. In the Plugin Inspector:

• Disable Any Platform.
• In Include Platforms, disable Editor and Standalone (keep the rest).

That’s it — once the analyzer is picked up, you’ll see the generated files under Analyzers and the __GeneratedInjector types will confirm SG is being used.
