Client-Side CommunicationException while Service works properly

Question

Currently i am facing a problem i do not understand. I have an wcf client that calls a wcf service through several threads at the same time (both on the same machine). Somet

Answer 1

Try to enable tracing at WCF side, you would get detailed information as to what is happening at server side.

Also sometimes WCF channel factory is closed abruptly when client sending big number of requests. we faced similar issue when we have used certificate authentication with WCF. In that we have deviced RetryPolicy around this transient error. if we get this error, we abort channel factory, recreate and send again rather than throwing exception.

 while (retryCount <= MAXRETRY)
            {
                try
                {
                    return _proxyService.GetData(); // _proxyService is WCF proxy class
                }
                catch (CommunicationException transientException)
                {
                     if (SLEEPINTERVAL> 0)
                    {
                        Thread.Sleep(SLEEPINTERVAL);
                    }
                    ((IClientChannel) _proxyService).Abort();
                    _proxyService = functionToCreateProxy();
                }

                retryCount++;
            }
