@phire If you're working in Visual Studio, Microsoft has done you the "favor" of turning on not only Copilot, but IntelliCode, which is the much sneakier local version of it.
It took me weeks to understand that IntelliCode was NOT IntelliSense, and was the reason behind all of the frustrating garbage literally no programmer would ever think of being suggested to me. I stumbled on it completely by force of sheer spite and had to look it up when I was going through my components one by one to see what I'd missed.
Uninstalling that shit and falling back to IntelliSense was like crushing the most annoying fucking bug I've had in literal years.
