C# 创建回调WCF服务时EndpointNotFoundException

我正在尝试基于的WCF回调服务的自托管

以下是托管代码：

服务：

static void Main(string[] args)
    {
        using (ServiceHost host = new ServiceHost(typeof(Message), new Uri("http://localhost:8000/HelloWCF")))
        {
            // Set up a service endpoint [Contract, Binding, Address]
            host.AddServiceEndpoint(typeof(IMessage), new WSDualHttpBinding() { ClientBaseAddress = new Uri("http://locahost:8001/HelloWCF") }, "HelloWCF");

            // Enable metadata exchange
            ServiceMetadataBehavior smb = new ServiceMetadataBehavior() {HttpGetEnabled =true };

            host.Description.Behaviors.Add(smb);
            host.Open();

            Console.WriteLine("Ready...");
            Console.ReadLine();
        }
    }

客户：

                    </security>

                </identity>
            </endpoint>
        </client>
    </system.serviceModel>
</configuration>

内部异常是：无法连接到远程服务器

这不是因为防火墙，因为我在没有回调函数的情况下成功测试了一个类似的应用程序

这可能是什么原因

完整的源代码可以在这里下载：

您似乎在托管您的端点，但您的客户端配置指向（注意：extra“/HelloWCF”）

更新

---

您的客户端配置契约设置为

CallbackService.IMessage

，但您的代码中没有IMessage契约的服务实现。

另外，我喜欢您的计算机/域名BadasComputing另外，我喜欢您的计算机/域名BadasComputing如果我将客户端端点设置为，内部异常将更改为404。服务器正在运行IMessage是服务器端接口。它希望向IMessageCallback发送回调消息，IMessageCallback在客户端上实现。因此，您可以为该接口包含服务契约和服务实现代码吗？如果我将客户端端点设置为，则内部异常将更改为404。服务器正在运行IMessage是服务器端接口。它希望向IMessageCallback发送回调消息，IMessageCallback是在客户端上实现的。那么，您是否可以包含此接口的服务契约和服务实现代码？通过这些更改，我得到了“HTTP无法注册URL HTTP://+：80/Temporary_Listen_Addresses/9b0d36c7-c04e-4204-9a7c-eb887b03f3c9/，因为TCP端口80正被另一个应用程序使用。“如果您只是将ClientBaseAddress更改为其他端口，您应该可以。我自己刚刚意识到。添加ClientBaseAddress=”“到配置/system.serviceModel/bindings/wsDualHttpBinding/binding已完成。我的错误是设置clientBaseAddress=“”，通过这些更改，我得到了“HTTP无法注册URL HTTP://+：80/临时_Listen_Addresses/9b0d36c7-c04e-4204-9a7c-eb887b03f3c9/，因为TCP端口80正被另一个应用程序使用。”如果您只是将clientBaseAddress更改为其他端口，您应该可以。我自己刚刚意识到这一点。向configuration/system.serviceModel/bindings/wsDualHttpBinding/binding添加clientBaseAddress=“”已完成。我的错误是设置clientBaseAddress=“”
