Sometimes even long error messages don't tell you much. This one is over 300 characters long and still does not clearly indicate what is wrong:Invoke operation '...' failed. Error in deserializing body of request message for operation '...'. OperationFormatter encountered an invalid Message body. Expected to find node type 'Element' with name '...' ......

It looks like Silverlight 5's ComboBox is more restrictive.
