title: How to get a thumbnail of a window in C#?
body: <p>How do you go about getting a thumbnail of a window, like Windows 7 superbar preview, or Aero flip? Note that I do not want a screenshot of the application, there is a way in DWM to get this information.</p>
  
  <p>I would like a C# way of doing this.</p>
  
  <p>Thanks</p>
