title: Which language was used to create Windows 8?
body: <p>I was seeing a video of <a href="http://www.youtube.com/watch?feature=player_embedded&amp;v=vsNwHoM7txs" rel="nofollow">Windows 8 demonstration</a>.</p>
  
  <p>So I was wandering which language was used to produce this new appearance: C++ or C#?</p>
  
  <p>Is there a WPF running on that UI?</p>
