Windows Phone e gli effetti di transizione

Grazie al phone toolkit avete a disposizione degli effetti di transizione molto carini e semplici da usare.

xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit"

Aprite il file "App.xaml.cs" e come prima cosa dovete cambiare il metodo InitializePhoneApplication(), in particolare la riga 

 private void InitializePhoneApplication()
        {
            if (phoneApplicationInitialized)
                return;

            // Create the frame but don't set it as RootVisual yet; this allows the splash
            // screen to remain active until the application is ready to render.
            RootFrame = new TransitionFrame();
            RootFrame.Navigated += CompleteInitializePhoneApplication;

            // Handle navigation failures
            RootFrame.NavigationFailed += RootFrame_NavigationFailed;

            // Handle reset requests for clearing the backstack
            RootFrame.Navigated += CheckForResetNavigation;

            // Ensure we don't initialize again
            phoneApplicationInitialized = true;
        }

"TurnstileTransition" è la tipologia di transizione applicata. Il toolkit ne mette molte altre a disposizione, divertitevi a provarle tutte.
