【问题讨论】：

你能分享你用于服务的代码吗？
您可能已将您的课程从 MinserviceWebb.Service1 重命名为其他名称，而无需更新 Service1.svc 标记页面
您在什么环境下工作？这是 IIS 服务器还是开发服务器？您是否尝试过将您的网络浏览器定向到相同的 URL？最后，我假设这 IS 托管在您尝试添加服务引用的同一台机器上
我只是调试 WCF，然后我遇到了这个问题，我将 Service1.cs 更改为另一个名称，但我遇到了同样的问题
@AliRiyadh（我假设您使用的是 Visual Studio）右键单击解决方案资源管理器中的 Service1.svc。单击“查看标记”。检查Service="Namespace.ClassName" 是否与您的类名称一致，以及CodeBehind="codefilename.cs" 是否与源代码的文件名一致

【解决方案1】：

可能是您的协议绑定。

仅打开了 https，并且您正在尝试通过 http 获取元数据。
