如何在vs2015中激活template10

using Template10.Common;

public App()
{
    InitializeComponent();
    Suspending += OnSuspending;
    Template10.Controls.SettingsService.UseShellBackButton = false;
    Template10.Controls.SettingsService.UseTitleBarBackButton = true;
    Template10.Controls.SettingsService.AutoRestoreAfterTerminated = true;
    Template10.Controls.SettingsService.ShowShellBackButton = true;
}

using Template10.Controls;

protected override async void OnLaunched(LaunchActivatedEventArgs e)
{
    if ((Window.Current.Content as ModalDialog) == null)
    {
        var nav = new NavigationService();
        nav.Navigate(typeof(MainPage));
        Window.Current.Content = new ModalDialog
        {
            DisableBackButtonWhenModal = true,
            Content = new Views.Shell(nav),
            ModalContent = new Views.Busy(),
        };
    }
    Window.Current.Activate();
    await Task.CompletedTask;
}

using Template10.Mvvm;

public MainPage()
{
    InitializeComponent();
    NavigationCacheMode = NavigationCacheMode.Required;
    ViewModel = new MainPageViewModel();
    DataContext = ViewModel;
}

using Template10.Mvvm;

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    ViewModel = new MainPageViewModel();
    DataContext = ViewModel;
    base.OnNavigatedTo(e);
}
