title: Wp7 Mango Clipboard access / upgrade project from 7.0 to 7.1
body: <p>The docs <a href="http://msdn.microsoft.com/en-us/library/ms597043%28v=VS.96%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/ms597043%28v=VS.96%29.aspx</a> state the System.Windows.Clipboard should be available in Windows Phone 7.1. I tried using it in the Visual Studio Express 2010 (beta 2 for Mango from June) but when </p>
  
  <p>using System.Windows.Clipboard;</p>
  
  <p>VS complains :</p>
  
  <p>Error   1   The type or namespace name 'Clipboard' does not exist in the namespace 'System.Windows' (are you missing an assembly reference?)</p>
  
  <p>Do I miss anything or is this just not ready yet?</p>
  
  <p><strong>UPDATE:</strong>
  Seems to work if I start a new project targetting Windows Phone 7.1 from the beginning. I just don't know how to change the setting from 7.0 to 7.1...</p>
  
  <p>Thanks a lot!
