title: wpf documentviewer to view different file formats?
body: <p>I have a wpf application where the user can upload files with different formats (for now only pdf).  I want to use document viewer to let the user see what's been uploaded.  Is this possible?   If this is not possible, can you suggest an alternative?  If this is possible, is this a good solution for this?</p>
  
  <p>Thanks,
  Angela</p>
