找不到WCF Resful服务错误方法

Question

我在WCF Restful服务上遇到错误。

我正在传递网址= http://localhost:16679/SayHelloService.svc/SayHelloMessage

 [ServiceContract]
public interface ISayHelloService
{
    [OperationContract]
    [WebInvoke(Method ="Get", 
               UriTemplate = "/SayHelloMessage", 
               RequestFormat =WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml,
               BodyStyle =WebMessageBodyStyle.Wrapped)]
    string SayHello();
}

实施

public class SayHelloService : ISayHelloService
{
    public string SayHello()
    {           
        return "Hello! This is Hello Message From EBS Middleware Service App ";
    }
}
