【问题描述】：

我正在制作一个带有服务的 Silverlight 程序。一切正常，但是当我昨天启动程序时出现此错误： CommunicationException is unhandled by user code, the remote server returned an error: NotFound 我的代码以前工作过，我没有对其进行任何更改。知道这可能是什么吗？以及如何解决。

{System.Net.WebException: The remote server returned an error: NotFound. ---> System.Net.WebException: The remote server returned an error: NotFound.

摘自a previous SO answer of mine：

'NotFound' 是一个通用错误消息，可能意味着任何事情。

无论如何，我发现对于跟踪此类问题非常宝贵的是 Microsoft 的 Service Trace Viewer 工具。阅读所有相关信息right here，只需对 web.config 进行一些简单的更改即可启用日志记录。
