title: Generating Client Callback Service Interface For WCF
body: <p>HI</p>
  
  <p>I am trying to follow the following article <a href="http://msdn.microsoft.com/en-us/library/ms731064.aspx" rel="nofollow noreferrer">http://msdn.microsoft.com/en-us/library/ms731064.aspx</a> , but i cant seem to generate the Client Callback Interface. I am using VS 2008.</p>
  
  <p>Not sure what is causing it , because 2 separate articles that i tried give the same prob.</p>
  
  <p>Thanks</p>
