Set the Timeout of a Callback in a Polling Duplex WCF Service

Question

I have a WCF service with a CallbackContract. The service is exposed to a Silverlight client using "pollingDuplexHttpBinding" When the Silverlight client is "dead" and the service calls a callback operation, it gets a timeout exception after one minute. How can I set this timeout to be different?

Thanks, Elad

Answer 1

So it seems that the "SendTimeout" attribute of PollingDuplexHttpBinding does the job:

<extensions>
  <bindingExtensions>
    <add name="pollingDuplexHttpBinding" type="System.ServiceModel.Configuration.PollingDuplexHttpBindingCollectionElement, System.ServiceModel.PollingDuplex, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
  </bindingExtensions>
</extensions>

<bindings>

  <pollingDuplexHttpBinding>
    <binding name="myPollingDuplex" sendTimeout="00:00:05"/>
  </pollingDuplexHttpBinding>

</bindings>


<services>
  <service name="Kodak.Pgy.Server.Event.WCFService.EventService" behaviorConfiguration="EventBehavior">

    <!--For duplex communication with the service from silverlight client-->
    <endpoint address="/for-silverlight" binding="pollingDuplexHttpBinding" bindingConfiguration="myPollingDuplex" contract="IEventService"/>

  </service>

</services>
