Where to Report C# Debugger Issues - Custom Host with CoreCLR Runtime

[Liangjia0411]

Hello,

I'm developing a project where I've created a custom host that integrates with the CoreCLR runtime, and I'm trying to use Visual Studio to debug C# programs running in this environment. I've encountered some debugging-related issues, but I'm unsure which team or repository I should submit these issues to.

When attempting to debug this managed code using Visual Studio, I'm experiencing issues related to AssemblyLoadContext (ALC) unloading:

1. When debugging code where an ALC has been marked for unloading but hasn't actually been unloaded yet:

   • DebuggerDisplay functionality shows incorrect information
   • Hovering over variables in the editor shows incorrect values
   • However, values displayed in the Variables window are correct
   • This issue occurs frequently but is not 100% reproducible

2. There are no issues when no "old" ALCs pending unload are present in the process

Thank you for your help!
