Remarks

Asynchronous methods inherited from the Web service proxy base class are not supported over DCOM. This includes the Begin\End and Async\Completed patterns. More specifically any asynchronous method names that start with Begin or End or end with Async are not supported. Any asynchronous events that end with Completed are not supported.
