无法调试WCF服务应用程序当WebMessageFormat是Json时

Question

我无法调试WCF服务App。来自visual studio 2012，当我尝试播放时，它给了我以下错误。

  

＆＃34;无法添加服务。可能无法访问服务元数据。使   确保您的服务正在运行并公开元数据。＆＃34;

请注意，当我将Operation Contract中的WebMessageFormat更改为Json

时，我收到此错误

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "getServicesSubList")]

的Web.Config
