.net 网络服务错误

Question

我正在 silverlight 中制作一个带有服务的程序。 一切工作正常，但是当我昨天启动程序时，出现此错误：CommunicationException 未由用户代码处理，远程服务器返回错误：NotFound 我的代码之前已经运行过，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。

摘自我之前的回答：

“NotFound”是一条通用错误消息，可能意味着任何事情。

无论如何，我发现 Microsoft 的 Service Trace Viewer 工具对于跟踪此类问题非常有用。 在这里阅读所有相关内容，所需要做的只是一些简单的更改添加到您的 web.config 以启用日志记录。
