Until the Cursor team fixes their C# extension to allow debugging tests, we can work around the limitation with only the launch.json file.
I created an example repo to demonstrate how this works. I wanted a simple one-click solution - no manual interaction - to start debugging my tests. It’s all detailed in the repo README file.
Feedback welcome! If there’s an easier way and/or I just overlooked some fundamental concept that obviates the need to for this solution, please let me know.
