In .NET it's even advanced to the point that the official C# and Visual Basic (and maybe others) compilers expose this functionality themselves, so that the IDE doesn't have to implement its own parser that may or may not understand things the same way.

Contrast with, e.g., working with Scala in IntelliJ, where you just have to kind of get used to the fact that the IDE will occasionally insist six ways from Sunday that your working code couldn't possibly compile.
