title: Cross fade page transitions Windows phone 8 toolkit
body: <p>I'm implementing the NavigationTransition with the TransitionService provided by the Windows Phone 8 toolkit and Microsoft.Phone.Controls. I was expecting the pages to cross fade during the transition but they don't crossfade by default. </p>
  
  <p>For instance if I'm going back to a previous page using a fade out transition, the origin page fades to full opacity before the target page appears, producing a "popping" effect. </p>
  
  <p>I hoping that someone could provide guidance on getting that effect to happen.</p>
