• Navigation: FragmentNavigation, LoadCompleted, Navigated, Navigating, NavigationProgress, NavigationStopped, NavigationFailed, GetCookie.

Codes : App.xaml.txt, App.xaml.cs.txt, MainWindow.xaml.txt, MainWindow.xaml.cs.txt

Activated is not raised for XAML browser applications (XBAPs).

Step: 1 Create a new project

The IDE creates two classes , MainWindow and App

Code in App.xaml.cs

The Clicking Exit button, would shut down the current application. However this can be overridden with a method in App class " App_Exit"
