<StackPanel x:Name="LayoutRoot" >
    <StackPanel.Resources>
        <Storyboard x:Name="myStoryboard">
                <DoubleAnimation From="1" To="2" Duration="00:00:1" 
                Storyboard.TargetName="myScaleTransform" 
                Storyboard.TargetProperty="ScaleX">
                <DoubleAnimation.EasingFunction>
                    <BackEase Amplitude="0.3" EasingMode="EaseInOut" />
                </DoubleAnimation.EasingFunction>
            </DoubleAnimation>
        </Storyboard>
    </StackPanel.Resources>

    <Rectangle Margin="60" x:Name="myRectangle" PointerPressed="Pointer_Clicked"
