We have some issues when load some asseblies which is built based on .net6 and some depedencies to system** binaries like "System.Drawing.Common".
Tried to add the dependecy path into %PATH%, not working:
Unhandled exception. System.BadImageFormatException: Could not load file or assembly 'System.Drawing.Common, Version=6.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'. Reference assemblies should not be loaded for execution. They can only be loaded in the Reflection-only loader context. (0x80131058)
And found the same issue to run demo\helloform.py if set PYTHONNET_RUNTIME=coreclr
Minimal, Complete, and Verifiable example
this will help us understand the issue.
