Does this stop you from using Cursor

No - Cursor works, but with this issue

Thanks for the report. A fix for quick fixes not applying went out in 3.16.17, which is the version in your report, so I want to pin down which side of that you’re on before we dig further.

Could you check three things?

  1. Fully restart Cursor, then try Ctrl+. on a C# error again and let me know if
    it still does nothing.
  2. Which C# extension are you using?
  3. If it still reproduces, open Help > Toggle Developer Tools, trigger the quick
    fix, and paste anything that shows up in the Console tab.

If it’s still happening on 3.16.17 that’s useful to know, and I’ll get it in front of the team.

  1. After a full Cursor restart, Ctrl+. still reproduces. The Quick Fix list appears. The first selected action applies. The second time the list appears again, but selecting an action does nothing.

  2. C# extension: anysphere.csharp v1.0.1 (Cursor’s bundled C#).
