title: Microsoft.Windows.Shell Namespace equivalent in .Net 4.5
body: <p>I am evaluating the code named <a href="http://www.codeproject.com/Articles/254120/Prism-4-MEF-Application" rel="nofollow">Prism 4 MEF Application</a> It is a .Net 4.0 application and has a reference to <a href="http://msdn.microsoft.com/en-us/library/microsoft.windows.shell" rel="nofollow">Microsoft.Windows.Shell Namespace</a> which is available if you install <a href="http://msdn.microsoft.com/en-us/library/ff806375" rel="nofollow">Microsoft Ribbon for WPF control</a>.</p>
  
  <p>However, I am working on .Net 4.5 framework, the ribbon control is somehow added to the framework, I can use it with a reference to DLL and with <code>System.Windows.Controls.Ribbon</code> namespace not <code>Microsoft.Windows.Controls.Ribbon</code></p>
  
  <p>Is there any equivalent control in .net 4.5 and how can I reference it?</p>
