您好，

今天在我开始处理我的应用程序之前，我更新了我的 WinXP.安装所有更新后，我的 WCF 服务停止工作.当我尝试在浏览器中打开 service.svc 文件时出现以下错误:

today before I start working on my application I updated my WinXP. After all updates have been installed my WCF service stop working. There is a following error when I try to open service.svc file in the browser:

Configuration Error

我的同事在更新之前尝试运行相同的服务，并且运行良好.安装更新后，他遇到了同样的问题.有人可以帮我吗?

The colleague of mine tried to run the same service before update and it works fine. He has the same problem after installing updates. Can someone please help me?

推荐答案

到目前为止，问题确实似乎来自更新 KB982168 并且仅在 2003 服务器上.Microsoft 支持人员怀疑 HttpTransportSecurity 构造函数中存在错误，该构造函数试图实例化 ExtendedProtectionPolicy 对象，但该类在 2003 服务器(或 XP 计算机)上的 system.dll 中不存在(您可以使用反射器检查).它确实存在于 2008 或 Vista 及更高版本的 DLL 中.如果问题得到确认，我想很快就会发布一个修补程序.同时建议不要安装更新.我会及时通知您.

So far, the problem indeed seems to come from the update KB982168 and only on 2003 servers. Microsoft support suspects a bug in the HttpTransportSecurity constructor that tries to instantiate a ExtendedProtectionPolicy object, but this class does not exist in system.dll on a 2003 server (or XP machines) (you can check with reflector). And it is indeed present on the DLL on a 2008 or Vista and above. If the problem is confirmed, I think there will be a hot fix released very soon. Meanwhile it is recommended to not install the update. I'll keep you informed.
