2、自定义 Silverlight 程序的启动界面，并显示加载进度
启动界面的 xaml 文件
SplashScreen.xaml

<Grid xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Background="Bisque"
>
<StackPanel Orientation="Horizontal" HorizontalAlignment="Center" VerticalAlignment="Center">
<TextBlock Text="Loading <TextBlock x:Name="percent" Text="0%" Margin="3" />
</StackPanel>
</Grid>
Silverlight 程序全部加载完成前，显示启动界面并显示加载进度
SplashScreen.html

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<body>
<div id="silverlightControlHost">
<object id="xaml1" data="data:application/x-silverlight-2," type="application/x-silverlight-2"
width="100%" height="100%">
<param name="source" value="../ClientBin/Silverlight20.xap" />

<iframe style='visibility: hidden; height: 0; width: 0; border: 0px'></iframe>
</div>

</body>
</html>
