I have to admit it's been a bit but when I first made the transition after a couple years using JetBrains, everything I actually used in Visual Studio was in VsCode. I should also admit that a big part of Microsoft strategy from as far back as 2003 was to make things "easy" in a non-translatable way which kept people locked into Visual Studio. Having traversed this divide, I see it now as something akin to different languages for the same concepts. Not unlike learning further programming languages after your first.
