How does the timeout work?  If the client is alive and responding, it shouldn't ever time out, right ?  Or am I wrong, is the session basically only good for whatever duration you set at the beginning?

Is there a way on the client side to determine if you've been timed out and to reconnect ?

# re: Silverlight Tip: Problems with polling duplex inactivitytimeout.

cool.. It worked. btw, I put ReceiveTimeout on PollingDuplexHttpBinding, and it's working fine..

PollingDuplexHttpBinding polling = new PollingDuplexHttpBinding();

polling.InactivityTimeout = TimeSpan.FromHours(1);

polling.ReceiveTimeout = TimeSpan.FromHours(1);

btw, How can I put it in infinite loop?

# re: Silverlight Tip: Problems with polling duplex inactivitytimeout.

Hi there,

I wrote a WCF server which generates a number each second (selfhosting console application). I sucessfully connected my silverlight 4 app to it and display the number the server pushes to the callback. This works for 10 minutes, afterwards client and server stop to produce/display any further numbers. I set the InactivityTimeout AND the ReceiveTimeout on the client side. It doesn't affect the timeout, though. Can anybody provide a working example where a silverlight client really gets updates after 10 minutes? Or do I have to set these timeouts on the server side? How can I do this in the config file?

Regards,

Stefan

@Stefan:

I believe the PollingDuplexHttpBinding.InactivityTimeout and .ReceiveTimeout properties need to be set on both the client- and server-side bindings. I can increase the length of time (10 mins default) before which the duplex messages stop (by increasing the properties mentioned above), but I don't understand why it times-out at all since our server-side code is sending a message every 30 seconds.

Scott

# re: Silverlight Tip: Problems with polling duplex inactivitytimeout.

I was able to have it run for more that ten minutes by setting three different parameters to the following:

var binding = new PollingDuplexHttpBinding(PollingDuplexMode.MultipleMessagesPerPoll);

binding.ReceiveTimeout = TimeSpan.MaxValue;

binding.InactivityTimeout = new TimeSpan(24,0,0,0); //maximum is 24 days

and in the web.config file I changed  serverPollTimeout="Infinite".

I agree with Scott Edmondson  too, Do you find any other solution?

I set my silverlight codes according to abovementioned method. But I never got it run over 10 minutes.

Please one successfully running the settings give a suggestion. Thanks,

Di

# re: Silverlight Tip: Problems with polling duplex inactivitytimeout.

Finaly we've made it working after many hours of problems. The only way it is working is after client bindings time outs are increased, and configuration in Web.config is proper with set both inactivity and receive timeouts.

example in Web.config:

...

     <pollingDuplexHttpBinding >

       <binding name="multipleMessagesPerPollPollingDuplexHttpBinding"

                duplexMode="SingleMessagePerPoll"

                inactivityTimeout="00:03:00"

                receiveTimeout="10:00:00"

                maxOutputDelay="00:00:07"/>

     </pollingDuplexHttpBinding>
