Copilot in Visual Studio is so hit or miss that frequently it's not worth using.

Today I asked it to add a constant as an argument to every call to a specific method in a unit test. The result was pure slop: The prompts leaked out into the proposed diff, and there was just a list of every method call, not placed where the method calls were in the unit test.

Just get the darn stuff to work before you shove it into every corner of my life.
