How do you get breakpoints to work in a code analyzer project?

Question

I created a code analyzer solution using the Analyzer with Code Fix (.NET Standard) template in VS 2022. I set the VSIX project as the startup project and run it. Using the basic example code unchanged, I can run it and see that the analyzer is working and the code fix is working. If I set breakpoints in the code fix project methods and do something in the editor to invoke the code fix, the breakpoints do get hit and it stops on them as expected. However, if I set breakpoints in the code analyzer methods, they are never hit even though they are showing as active. So, the question is how do I get the breakpoints to work in the code analyzer project so that I can step through and debug the code I write for the analyzer?
