If you're going heavy into AI coding with C# (like approaching 100% AI code), give my 5 part writeup a read. Battle tested configuration with a fast moving team that was pretty much 100% AI code with good code quality.

It's the difference between an ultrasound and reaching in and manipulating the organ.
