Adding animated page transitions to your app can help it look more polished and, when used modestly, can increase the user’s perception of the quality of your app.
The Windows Phone Toolkit includes a set of classes that make it easy to add animated page transitions. The Toolkit is discussed in depth in Chapter 9, “Enriching the User Experience with the Windows Phone Toolkit Controls.”
Within the Toolkit, transitions are defined by assigning a transition effect represented by
TransitionElement objects such as
TurnstileTransition to various transition events. These events occur during navigation and indicate the direction of the navigation (see Figure 4.5).
