If you can provide a\r\n    [Minimal, Complete, and Verifiable example](http://stackoverflow.com/help/mcve)\r\n    this will help us understand the issue.\r\n\r\n1. Create a pytest test file that looks like this:\r\n\r\n```python\r\nimport clr\r\n\r\nclr.AddReference(r\"c:\\some_net_dll.dll\")\r\n\r\ndef test_just_a_dummy():\r\n    assert 1 == 1\r\n```\r\n2. Replace the reference to a DLL above to a real .net DLL that loads fine when the above file is just run using regular python.exe.\r\n3. Use VS Code test discovery, or just call `pytest --collect-only`\r\n\r\n-   If there was a crash, please include the traceback here.\r\n\r\n```\r\n============================================================= test session starts =============================================================\r\nplatform win32 -- Python 3.6.0, pytest-5.3.1, py-1.8.0, pluggy-0.13.1\r\nrootdir: C:\\Users\\me\\source\\repos\\utils-tester\r\ncollecting ...
