部署的WCF Silverlight应用程序返回404错误

我有一个Silverlight 5 Web应用程序，我在IIS 8中托管。我可以在VS 2013中运行我的应用程序，但在部署到运行IIS 8的Windows 2012服务器时，我的应用程序无法运行。Fiddler给了我以下内容:描述:HTTP 404。您正在查找的资源(或其依赖项之一)可能已被删除、名称已更改或暂时不可用。请查看以下网址，并确保拼写正确。

我的网页。配置文件如下所示:

有人能告诉我为什么以前配置的Win 2012服务器现在不加载部署的应用程序，而我仍然可以从VS 2013运行?或者有没有办法让Fiddler给出更详细的错误?

我设置了跟踪，但是日志没有给出任何更好的线索。

谢谢。
