title: Update service reference error
body: <p>I am trying to update the service reference in my silverlight application to a web service that I have just updated to target version 4 framework. </p>
  
  <p>When it was running on version 3.5 and I made any changes, then updated in the client, it working fine however since changing the web service target framework I am getting an error stating that there was an error downloading the web service URL.</p>
  
  <p>How can I update the service reference after changing the framework?</p>
