    <p>for notification in my silverlight client app, I am using WCF pollingDuplex binding.</p> <p>Binding Details at server side ...</p> <pre><code>PollingDuplexHttp Binding custPollBind = new PollingDuplexHttpBinding(); custPollBind.InactivityTimeout = TimeSpan.FromDays(12); custPollBind.ReceiveTimeout = TimeSpan.FromDays(12); custPollBind.ServerPollTimeout = TimeSpan.FromSeconds(25); custPollBind.TransferMode = TransferMode.StreamedResponse; custPollBind.MaxOutputDelay = new TimeSpan(0, 0, 7); </code></pre> <p>Binding Details At Client Side :</p> <pre><code> PollingDuplexHttpBinding binding = new PollingDuplexHttpBinding() { ReceiveTimeout = TimeSpan.FromDays(12), InactivityTimeout = TimeSpan.FromDays(12), }; EndpointAddress address = new EndpointAddress(endPoint); client = new StuDuplexServiceClient(binding, address); </code></pre> <p>I want channel should never go into fault stat.</p> <p>For this , also on every minitue I am sending some dummy notification data to keep all connected client or channel alive.</p> <p>It is working fine. But After long duration usually 4-5 or 5-6 or some time 2-3 hours all connected channel getting faulted. ANd client app is no more connected to WCF service.</p> <p>Once after long duration , if I am refreshing the page or re-connecting the client app, it is connecting , but again after only 10-12 seconds , channel is becoming faulted state. and you can say , it is connecting for only 10-12 seconds.</p> <p>If again I am re-starting my service , then it is working fine. and same problem is contud.... after some time.</p> <p>My WCF service is hosted as Windows service.</p> <p>For Service Behavior I am using this..</p> <pre><code>[ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple, InstanceContextMode = InstanceContextMode.Single)] </code></pre> <p>Is this creating any problem. I have checked by removing this also. but there is no luck.</p>

    1. COHave you tried to set `ReceiveTimeout` in the HttpTransportBindingElement?

    3. COI used the CustomBinding class with the PollingDuplexBindingElement and the HttpTransportBindingElement elements. Also I set both timeouts to 20hours and TransferMode had default value (Buffered I think).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
