A Page can only get a reference to its NavigationService when Page raises the Loaded event. If you subscribe to loaded event of the page, then you will get NavigationService instance.

public Home()
    {
        InitializeComponent();
        this.Loaded += (s, e) =>
                           {
                               var ns = NavigationService;
                               ns.Navigate(new Uri("/About", UriKind.Relative));
                           };
    }
