        }

        public override void Send(SendOrPostCallback d, object state)
        {

            SyncWorkQueueItem syncQueueItem=new SyncWorkQueueItem(d, state);

            ThreadPool.QueueUserWorkItem(new WaitCallback(syncQueueItem.Invoke), null);

            //-- Auf das Ende der Operation warten und ggf. Exceptions erneut werfen
            syncQueueItem.Join();
            syncQueueItem.RethrowException();
        }
