I don’t know about "just complaining" - this is an opinion with which I do not agree :)
However, VB.NET background compilers (and possibly Resharper C #) do not actually build complete assemblies - they cannot! If you think about it, the natural state of your code does not compile at run time! Almost every keystroke puts your code in an invalid state. Think about this line:
var x = new Something();
, "v" "), " ". , , ? , , , ?
, "", - , , , .. , , "", .
