在App.xaml中：

<VisualState x:Name="Open"> 　　<Storyboard> 　　　　<DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"> 　　　　　　<EasingDoubleKeyFrame KeyTime="0" Value="90"/> 　　　　　　<EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/> 　　　　</DoubleAnimationUsingKeyFrames> 　　</Storyboard> </VisualState>

其次，在<Grid x:Name="ContentRoot"...> 中加入：

<Grid.Projection><PlaneProjection/> </Grid.Projection>

?下面是兩個窗口翻轉出現的例子：A窗口在前為調用窗口，B窗口在后為被調用窗口。

A窗口在app.xaml中的樣式：

<VisualStateGroup x:Name="AnimationStates"><VisualState x:Name="WindowShow"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState><VisualState x:Name="WindowHide"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0" Value="0"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="90"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState></VisualStateGroup>

B窗口在app.xaml中的樣式：

<VisualStateGroup x:Name="WindowStates"><VisualState x:Name="Open"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0:0:0" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="-90"/><EasingDoubleKeyFrame KeyTime="0:0:1" Value="0"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState><VisualState x:Name="Closed"><Storyboard><DoubleAnimationUsingKeyFrames Storyboard.TargetProperty="(UIElement.Projection).(PlaneProjection.RotationY)" Storyboard.TargetName="ContentRoot"><EasingDoubleKeyFrame KeyTime="0:0:0" Value="0"/><EasingDoubleKeyFrame KeyTime="0:0:0.5" Value="90"/></DoubleAnimationUsingKeyFrames></Storyboard></VisualState></VisualStateGroup>

A窗口中某一個按鈕的代碼：

private void button1_Click(object sender, RoutedEventArgs e){VisualStateManager.GoToState(this, "WindowHide", true);WinB w = new WinB();w.Show();w.Closed += new EventHandler(w_Closed);}void w_Closed(object sender, EventArgs e){VisualStateManager.GoToState(this, "WindowShow", true);}

?另外，RotationY的值為：

0：向前；

180：向后；

90：向左；

-90：向右。
