title: The type or namespace name 'Syndication' does not exist in the namespace 'System.ServiceModel' After updating to VS2010
body: <p>i get the following error when trying to compile my asp.net site after updating the project from vs2008 to vs2010</p>
  
  <p>The type or namespace name 'Syndication' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)</p>
  
  <p>I have the asp.net site targeting 3.5 framework (as it did in vs2008)
  I also added a reference to System.ServiceModel.Web</p>
  
  <p>I also have these using statements at the top of my class:
  using System.ServiceModel;
  using System.ServiceModel.Description;
  using System.ServiceModel.Syndication;
  using System.ServiceModel.Web;</p>
  
  <p>The last 2 complain with the error above, commenting them out produces errors (cannot find WebGet, etc.) like it flipflops.</p>
  
  <p>Anyone have any ideas?</p>
