title: Which GUI Library does Microsoft use for Visual Studio?
body: <p>I am currently looking for a good C++ GUI Lib for Windows and thought I will pick one where I can see how powerfull it is (I dont like qt..).</p>
  
  <p>So is Visual Studio itself programmed with win32/MFC or did they createt another GUI Lib for this (and similar) purposes? If yes which did they used?</p>
  
  <p>Regards</p>
