NavigationInTransition这个是实现页面切换效果，而且没控件来拖，要自己手动写，

将App.xaml.cs中InitializePhoneApplication()函数里的RootFrame进行修改

RootFrame=new TransitionFrame();

有五种动画效果

1.RollTransition（卷：）

2.RotateTransition（旋转 ：类似（屏幕左右旋转）可设置顺时针方向，或者逆时针方向）

3.SlideTransition（滑：类似（上下进去屏幕））

4.SwivelTransition（旋转 ：类似（屏幕前后旋转））

5.TurnstileTransition(栅门:类似翻页效果)

 

写个案例：

xaml:

 <toolkit:TransitionService.NavigationInTransition>

        <toolkit:NavigationInTransition>

            <toolkit:NavigationInTransition.Backward>

                <toolkit:RotateTransition Mode="In180Clockwise"></toolkit:RotateTransition>

            </toolkit:NavigationInTransition.Backward>

            <toolkit:NavigationInTransition.Forward>

                <toolkit:RotateTransition Mode="In180Clockwise"></toolkit:RotateTransition>

            </toolkit:NavigationInTransition.Forward>

        </toolkit:NavigationInTransition>

    </toolkit:TransitionService.NavigationInTransition>

    <toolkit:TransitionService.NavigationOutTransition>

        <toolkit:NavigationOutTransition>

            <toolkit:NavigationOutTransition.Backward>

                <toolkit:RotateTransition Mode="Out180Clockwise"></toolkit:RotateTransition>

            </toolkit:NavigationOutTransition.Backward>

            <toolkit:NavigationOutTransition.Forward>

                <toolkit:RotateTransition Mode="Out180Clockwise"></toolkit:RotateTransition>

            </toolkit:NavigationOutTransition.Forward>

        </toolkit:NavigationOutTransition>

    </toolkit:TransitionService.NavigationOutTransition>

这个放在页面</phone:PhoneApplicationPage >的后面，由于是手动写的，要自己写引入silverlight命名空间，xmlns:toolkit="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone.Controls.Toolkit" 这个是在<phone:PhoneApplicationPage>里面
