WPF制作一个模仿Silverlight页面还有win8系统的Loading动画效果，其实就用到WPF的ellipse即可，如果想要简单或者更好的效果的话还是要用Blend去做哈。

xaml代码：

<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        x:Class="Loading动画.Window1" x:Name="Window" Title="Window1" Width="640" Height="480"
