This just takes a bit of a shift in thinking away from blocking/waiting to thinking in async terms on the WP7 platform. The result is the user is always able to interact with the UI.

Move a call to your completion code (writeline in this case) into your CompletedEventHandler and for any UI updates marshall back to the UI thread with

Dispatcher.BeginInvoke( () => { /* your UI update code */ } )

If there are any UI elements that should not be interacted with while your async op is executing then these controls can be hidden or disabled for the interim.
