I would like to perform a Session Logout before my Silverlight OOB application exits. I need to handle both the Close Button event as well as the user closing the Application from the taskbar. The DevForce Async calls are not executed in Application_Exit. Because I am also persisting the Entity managers to Isolated Storage in Application_Exit the Session Logout update is actually performed the next time I startup the application and the EntityManager is restored from IS. is there any way I can do this Session Logout update before the Application actually exits.
Thanks
Rick Adams

Rick,
From my research, it looks like this is a limitation with Silverlight,
and thus is something that we can't handle in DevForce. It looks like it
has to do with how calls are queued inside the UI thread. Have you
tried putting your async code into a separate thread and locking your
current thread until that has completed? I don't think that the
application can exit until the UI thread is no longer locked. In your
case, you may want to combine this with a MessageBox, telling the user
that the application is exiting and that it may take a moment, rather
than letting them think it's timed out.
Yours,
Robert

Try doing it from the Application.MainWindow.Closing event, you can then execute your required code.
