Background worker with silverlight 5 makes wcf service calls stuck while running

Question

I am working with Backgorund worker. I have a Silverlight 5 application using WCF service.

When I call a background method it hits a service and this method takes some times to complete. During the time background worker is running, if i make some other service call it stops till the background method gets completed. I want to make parallel WCF service calls. I am not sure about the reason of the problem.

Is WCF hosted on IIS? – Alexei - check Codidact Apr 14 '16 at 19:45 — Alexei - check Codidact, Apr 14 '16 at 19:45

If your WCF is hosted in IIS, then the most probable cause of your second request not getting processed until the first WCF call is returned is the session lock put by IIS.

One way is to avoid using session for the processing or replacing with a custom session mechanism, as suggested in the above link.

If you provide more details about what your Background worker is trying to achieve, you might get a more targeted answer (i.e. maybe the processing can be done without locking the session).

Can you suggest some way? – Khan_Sobiya Apr 15 '16 at 17:19
Yes, but can you provide details about how WCF is hosted? How is the session implemented? My answer covers the case when using IIS and having a session, scenario which has the provided explanation. – Alexei - check Codidact Apr 15 '16 at 19:39
