// ここから
var opt = new CSharpParseOptions(kind: SourceCodeKind.Regular, documentationMode: DocumentationMode.Parse);
var driver = new CSharpGeneratorDriver(opt, ImmutableArray.Create<ISourceGenerator>(new Class1()), ImmutableArray<AdditionalText>.Empty);
driver.RunFullGeneration(compilation, out var resultCompilation, out _);
// ここまで
return resultCompilation;
}
}一応これでステップインできそう。
