title: How do I include System.Windows.Shapes?
body: <p>I am using Visual Studio 2008 with the .NET Framework (v3.5). I cannot seem to use System.Windows.Shapes, or anything System.Windows.* besides Forms. </p>
  
  <p>Here is the link to the class description:</p>
  
  <p><a href="http://msdn.microsoft.com/en-us/library/system.windows.shapes.aspx" rel="noreferrer">System.Windows.Shapes (MSDN Library)</a></p>
  
  <p>Is there some special thing I need to do to use it? </p>
  
  <p>I checked in all of the framework folders, and the only dll/xml files I have for System.Windows is System.Windows.Forms.</p>
  
  <p>What do I need to do to get this to work?</p>
