我有一个调用 2 个 WCF 服务的 VS2010 MVC3 解决方案。在我的第一台电脑上一切正常。我在另一台计算机上安装了相同的操作系统、相同的 VS、相同的 SQL Server Express、相同的 IIS……我在第二台计算机上复制了我的解决方案的源代码。运行解决方案时一切正常。
但是在第二台计算机上：
我无法浏览到服务 URL ！？(1)
我不能做“更新服务参考”！？(2)
(1) 当我浏览到http://localhost/PLATONServices/RequestService.svc时，我收到了 HTTP400 BAD REQUEST 错误。
(2) 我收到一个 HTTP 状态 400 的请求失败：错误的请求元数据包含无法解析的引用：'http://localhost/PLATONServices/RequestService.svc'。
任何想法？
因为两台计算机上的代码源相同，并且第一台计算机上一切正常，所以问题出在其他地方。我在两台计算机上都使用 IIS6，但看不到任何差异。
我搜索了一整天都没有成功。
谢谢。

这是WCF的踪迹：
