1. How can I exit or quit programmatically (through code) from my Windows Phone 8 app?

Answer 1

In WP8 there's a new API which lets you terminate the application:

Application.Current.Terminate();

By calling the method your app will immediatelly terminate. However the Application_Closing event won't be called, and IsolatedStorageSettings.ApplicationSettings dictionary won't be automatically persisted.

So if you have data hanging around in IsolatedStorageSettings.ApplicationSettings that you don't want to lose then it's wise to save it:

IsolatedStorageSettings.ApplicationSettings.Save();
Application.Current.Terminate();

Also the method should not be misused. See http://msdn.microsoft.com/en-us/library/windowsphone/develop/system.windows.application.terminate(v=vs.105).aspx for more info for legitimate use cases.

while (((PhoneApplicationFrame)App.Current.RootVisual).CanGoBack)
{
    ((PhoneApplicationFrame)App.Current.RootVisual).RemoveBackEntry();
}

In Windows Phone 8.1, the method has been renamed to

Application.Current.Exit();
