Debuging a Roslyn Analyser

Question

I have created a analyser and set breakpoints in the Initialize and AnalyizeSymbol methods. Built the project and run the Vsix. When set running another instance of Visual Studio is created. I create a new C# class library and attempt to update the class name. None of the breakpoints hit. I am using Visual Studio 2019 16.9.4.
Any ideals on why the breakpoints don't hit. I have looked at running extensions and the created analyser is present and running.

Hello @Cairn ,

Welcome to Microsoft Q&A forum.

I think, VS extension project for Roslyn Analyzer is a little different from other extensions.

Due to its function, you may need to use .Test project(the default name is [your project/solution name].Test) which is included in your analyzer solution, and write unit tests to validate every case works as expected.
