title: TFS SDK - Getting the network credential prompt
body: <p>I am trying to get the network prompt so that user can provide the credentials.
  I saw <a href="http://msdn.microsoft.com/en-us/library/bb130172%28v=vs.80%29.aspx" rel="nofollow">this</a> and It does not help. Could somebody provide a more complete example?
  The goal is is to get this from a Word Add-in so that I can create work items in TFS from the function points mentioned in the word document. So, somebody writes the function points in a document, closes it and It would ask for the network credentials so that It can create work items in the TFS.</p>
