title: Why one of the new method that i add is not available on WCF Test Client?
body: <p>I added a new method to an existing WCF service application. The method that I added returns a new class type. </p>
  
  <p>When I start the WCF Test Client the new method is greyed out and I see that the reason that this method is greyed out is because this method is returning the new class type. </p>
  
  <p>The method and the new class type are marked with DataContract &amp; DataMember. 
  There is no error - but next to the method name in the WCF test client I see the remark "this method is not available because it is using the class XXX" (XXX is the new class type that I defined).</p>
  
  <p>When I call this new method from the silverlight client I get the same result that I expected with the same new class type. </p>
