Does the PhoneApplicationPage_Unloaded event get called when the start button is pressed?

I do some clean up stuff in my PhoneApplicationUnloaded event on a xaml page. If I put a breakpoint inside the event, I can see that it gets hit if I use the backbutton to unload the page, or if I navigate forward anywhere, but if I use the start button to go back to the home screen, I don't see the breakpoint get hit.

Does this event really get called when you hit the start button? (maybe for some reason the emulator stops debugging when that happens and I don't see it get hit) or does it not. And if it doesn't what event should instead?

There's a good article on MSDN that explains what happens when Start button is pressed and which event you should bind to. Whenever the application gets interrupted (like by a phone call or start button), it gets tombstoned, and the associated Application_Deactivated event is raised. Whenever the focus gets back to your application, you get Application_Activated event (where you're supposed to restore previous state).

Hitting the start button doesn't unload the application, the other scenarios do unload the application. Put the code in your Unload event into a common class that both the Unload event and the button click event can call.
