Question

I have Silverlight application which connects to a WCF service.

If i open the open connection at the start of the application and then say give it 10 minutes or so before the client comes to call a method it will time out.

I understand that it is easy to change the timeout time in the web.config.

However what I’m looking for it for the WCF service to remain active to say 5 minutes after the soap client has been closed.
I though about maybe running a background thread in Silverlight which calls a WCF method which doesn’t do anything but this feels rather hacky.

Is there more of a professional way of doing this?

Thanks

You can change InstanceContextMode to signleton and start the service in the service constructor. Using signleton mode means that your session never expires.

[ServiceBehavior(InstanceContextMode=InstanceContextMode.Single)]

Another solution is changing the InstanceContextMode to PerSession and set the InactivityTimeout to something like 1 hour.

<bindings>
    <wsHttpBinding>
      <binding name="WSHttpBinding" >
        <reliableSession inactivityTimeout="01:00:00" enabled="true" />
      </binding>
    </wsHttpBinding>
  </bindings>

UPDATE(After reading your comment): You can also set the inactivityTimeout=”infinite”.
