起因:在写silverlight的功能时,需要从站点下载一些配置文件,单元测试在使用 silverlight tooltik(http://silverlight.codeplex.com/)时ok,使用statlight(http://statlight.codeplex.com/)时会发生错误,原因是statlight模拟了一个webserver,而这个模拟的webserver不支持文件下载。因此下载statlight代码对其进行了改进。
修改位置:Statlight.Core/WebServer/ResponseFactory.cs

注意:
1.在运行测试时要注意项目的启动目录
2.以及 silverlight 端只能使用相对路径访问。
