title: the name rtfwriter does not exist in the current context
body: <p>I'm trying to convert XML docs into rtf documents.<br>
  I can successfully perform xml to pdf conversions, but whenever I attempt to use <code>RtfWriter.GetInstance</code> or  <code>RtfHeaderFooters</code> I get the following error message:</p>
  
  <blockquote>
    <p>The name Rtfwriter does not exist in the current context </p>
  </blockquote>
  
  <p>I can't seem to access any of the rtf assemblies. Has anyone encountered similar problems or has a possible solution?</p>
  
  <p>Thanks</p>
