BrokeredMessage.CompleteAsync always gives ObjectDisposedException

message.CompleteAsync().ContinueWith(tr =>
                    {
                        if (tr.Exception != null)
                        {                       
                            Trace.TraceWarning("Failed to Complete BrokeredMessage \n" + tr.Exception.ToString());
                        }
                    });
