Loading Animation

A very simple loading animation in XAML format.
Create a simple loading in XAML:
<UserControl x:Class="ShineDraw.Controls.LoadingAnimation"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Width="400" Height="400" >
    <UserControl.Resources>
        <Storyboard x:Name="Rotation" RepeatBehavior="Forever">
            <DoubleAnimationUsingKeyFrames BeginTime="00:00:00" Storyboard.TargetName="LayoutRoot" Storyboard.TargetProperty="(UIElement.RenderTransform).(TransformGroup.Children)[2].(RotateTransform.Angle)">
