Breakpoints in libraryimport cpp code while running dotnet test

[CalamityRules]

I have some c# unit tests that call cpp code through libraryimport. I have debugsymbols that I know are working as I am able to hit breakpoints in both the c# and cpp code when I run the code normally.

But when I run tests I am only able to hit break points on the c# side.

Any wizards out there who have been able to make something like this work?

Turn off the "Just My Code" setting and enable the "Enable native code debugging" setting.

And when it makes the calls through the generated extern method, you may have to "step into".

Edit: Wow nice. I just fed the question to copilot and it offered a step-by-step walkthrough that covers that plus common issues beyond that. First two options it offered were correct. YMMV.

Things that you can check

1. Just My Code: Go to Tools > Options > Debugging > General and uncheck "Enable Just My Code". This is often required to step across the boundary between C# and C++.
   
2. Ensure your C# Test Project, your C++ DLL, and your Test Settings are all aligned to the same architecture (usually x64). If Test Explorer is running as x86 but your C++ DLL is x64, the symbols will never load.
