I've yet to have a good experience with copilot in Visual Studio
It still surprises me to have shows stopping bugs with it, In THE first party IDE, in Windows, using pure .NET and other microsoft tooling
I couldn't describe a more perfectly vacuum'ed spherical cow, and still, copilot dies randomly even after they have acknowledged the problem and made some fixes
Visual Studio unfortunately still heavily uses legacy .NET Framework, only some parts of instrumentation specifically for C# were moved out of process and run on top of modern runtime. It's a pretty good IDE, much better than the kind of experience you get elsewhere, but I've moved to VSC + Rider since and only use VS occasionally on my "gaming pc" because it has a convenient community-made extension for getting quick .NET's compiler output.
