Description
It is a very common bug for code to invoke extern methods or COM interface methods and disregard the error code that is returned from those methods. An analyzer that catches this would be immensely useful to many applications.
Error codes include:
- WIN32_ERROR
- HRESULT
- NTSTATUS

Research direction
The issue names no files, tests, or entry points. Start by locating the project's C# source-generator and diagnostic infrastructure, then determine how ignored WIN32_ERROR, HRESULT, and NTSTATUS return values should be identified and tested; done requires agreed behavior and coverage for those cases.
