tj62,

I've looked around and it seems it's not possible.

As per MS Documentation: (http://msdn.microsoft.com/en-us/library/system.windows.application.exit(v=VS.95).aspx)

An Exit event handler should not include long-running, re-entrant, or cyclic code, ...

Regards,

Thank you sbelini,

Just one question. The logout is performed asynchronously, so as I'm closing the applicatoin I do not have any means of waiting for the logout callback to be called. Is it possible to somehow force the application to wait for the callback .... or is it secured that the LogoutAsync() will go through to the server before the application shuts down?

The below call "persistenceGateway.Logout(null)" will call
p_manager.LogoutAsync(null,null);

private void Application_Exit( object sender , EventArgs e )

{

var persistenceGateway = m_bootstrapper.Container.Resolve<IPersistenceGateway>();

if(persistenceGateway.p_isLoggedIn)

persistenceGateway.Logout(null); // I set callback to null, as I do not know how to wait for it

}

Hi tj62,

You can use the Application Exit event (in the App.xaml.cs file).

Is it possible in the Silverlight Client code to somehow grab when the user closes the hosting browser (or browser page)?

I need this to do some cleenup work like saving to the database display states, etc.
I also wnat to do a logout to free resources on the server side that otherwise times out, if I have understood things right.
