How to list the whole object in the GC completion list?

Question

I have a crash in my program, this is a visualizer for VS, so it is very difficult to debug, I tried to dump and use WinDbg to study it, but it was unsuccessful.

So now I am trying to use this list programmatically, but I do not know how to do it. Thank.

Answer 1

I don’t think there is a way to get into the finalization queue through the .NET Framework Framework Class Library (FCL). I suspect that if you want to do this programmatically instead of debugging with WinDbg , you (like WinDbg and similar tools) will need to use the CLF unmanaged APIs for debugging and profiling for this purpose.

ICORDebugGCReferenceEnum COM-. ICorDebugProcess5::EnumerateGCReferences:
