  <p>describes that this should be possible and that you can even create the proxy using the 'Add Service Reference' after I right click on references. </p>
  
  <p>however, 'Add Service Reference' is not available. I also have tried to generate the Proxy using SLSVCUtil but than I get a lot of errors seeing that there is no System.ServiceModel available.</p>
