• Diagnostic Analyzers in Visual Studio 2015: First Look by Kathleen Dollard.

• Introduction to the .NET Compiler Platform by Bart De Smet.

• If you have a question about how to do something with Roslyn try out the Gitter channel for Roslyn.

• Explore the Roslyn Repo. Especially look into:

  • How To Write a C# Analyzer and Code Fix.
  • The Syntax Visualizer. This is an invaluable tool to help understand the syntax tree.
  • Analyzers and Localization. I also recommend looking at how localization is done on the project created by the default Visual Studio template for analyzers to get an idea of how it works.
  • .NET Compiler Platform (“Roslyn”) Overview.

• Since the .NET Compiler Platform is vast I recommend searching github for roslyn analyzers to get ideas and learn how to use it.

• Enable concurrent execution of your analyzers and prevent them from running in auto generated code by using the following in your diagnostic analyzer class:

  public override void Initialize(AnalysisContext context)
  {
          context.EnableConcurrentExecution();
          context.ConfigureGeneratedCodeAnalysis(GeneratedCodeAnalysisFlags.None);
          ...
  }
