title: FaceBook C# SDK in Windows 8 Release VS2012
body: <p>I downloaded this example about FB SDK C# for metro app at here:<br>
  <a href="https://github.com/facebook-csharp-sdk/facebook-metro-sample" rel="nofollow">https://github.com/facebook-csharp-sdk/facebook-metro-sample</a></p>
  
  <p>However, when we run it on VS 2012 express + Windows 8 Release Preview, it can't post status to wall after logging is complete.</p>
  
  <p>We get this error message: </p>
  
  <blockquote>
    <p>"A first chance exception of type <code>'System.TypeLoadException'</code> occurred
    in Facebook.DLL An exception of type <code>'System.TypeLoadException'</code>
    occurred in Facebook.DLL but was not handled in user code Additional
    information: Could not load type <code>'System.Text.Encoding'</code> from assembly
    <code>'System.Runtime, Version=4.0.0.0, Culture=neutral,
    PublicKeyToken=b03f5f7f11d50a3a'</code>."</p>
  </blockquote>
  
  <p>Does anyone have any idea on how to get this to run with VS2012?</p>
