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.
VS Code and Visual Studio have about as much in common as JavaScript and Java.
