WCF元数据包含无法解析的引用 [英] WCF Metadata contains a reference that cannot be resolved

问题描述

我已经花了几个小时寻找这个错误，我已经测试了几乎所有它在谷歌。

I've spent a couple of hours searching about this error, and I have tested almost everything it's on Google.

我想用TCP，.NET4和VS2010，在C＃中访问服务。

我有一个非常小的服务：

I Have a very tiny service:

namespace WcfService_using_callbacks_via_tcp
{
    [ServiceContract(CallbackContract = typeof(ICallback), SessionMode = SessionMode.Required)]
    public interface IService1
    {
        [OperationContract]
        string Test(int value);
    }

    public interface ICallback
    {
        [OperationContract(IsOneWay = true)]
        void ServerToClient(string sms);
    }
    [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
    public class Service1 : IService1
    {
        public string Test(int value)
        {
            ICallback the_callback = OperationContext.Current.GetCallbackChannel<ICallback>();
            the_callback.ServerToClient("Callback from server, waiting 1s to return value.");
            Thread.Sleep(1000);
            return string.Format("You entered: {0}", value);
        }

    }
}

有了这个Web.config文件：

With this Web.config:

这code主办的：

---

And this code to host it:

static void Main(string[] args)
{
    Uri base_address = new Uri("net.tcp://localhost:5050/Service1");
    ServiceHost host = null;
    try
    {
        // Create the server
        host = new ServiceHost(typeof(Service1), base_address);
        // Start the server
        host.Open();
        // Notify it
        Console.WriteLine("The service is ready at {0}", base_address);
        // Allow close the server
        Console.WriteLine("Press <Enter> to stop the service.");
        Console.ReadLine();
        // Close it
        host.Close();
    }
    catch (Exception ex)
    {
        // Opus an error occurred
        Console.ForegroundColor = ConsoleColor.Red;
        Console.WriteLine(string.Format("Host error:\r\n{0}:\r\n{1}", ex.GetType(), ex.Message));
        Console.ReadLine();
    }finally
    {
        // Correct memory clean
        if(host != null)
            ((IDisposable)host).Dispose();
    }
}

现在我要创建的客户端，但我是不是更多钞票。我用直接添加服务引用和SvcUtil工具，但我收到此错误：

---

Now I want to create the client, but I it is not posible. I've used Add Service Reference and svcutil directly, but I am receiving this error:

如果您想了解更多的帮助，请键入SvcUtil工具/？

If you would like more help, type "svcutil /?"

所以，我可以承载没有问题的服务，但我不能创建代理。

---

So, I can host the service without problems but I can not create the proxies.

我试过差不多，我发现任何配置，但我认为目前的web.config是正确的。有行为，安全性，和绑定使用MEX，由端点使用。

I've tried almost any config I've found, but I think the current web.config is correct. There are the behaviours, the security, and the bindings using mex, used by the endpoints.

我试图创建一个app.config并将其设置为与svcutil.exe的同一文件夹中。

I've tried to create an app.config and set it to the same folder with svcutil.exe.

推荐答案

您缺少服务配置

<system.serviceModel>
  <services>
    <service name="WcfService_using_callbacks_via_tcp.Service1" 
      behaviorConfiguration="Behavior_Service1">
      <host>
        <baseAddresses>
          <add baseAddress="net.tcp://localhost:5050/Service1" />
        </baseAddresses>
      </host>
      <endpoint address="" contract="WcfService_using_callbacks_via_tcp.IService1"
         binding="netTcpBinding" bindingConfiguration="DuplexNetTcpBinding_IService1" />
      <endpoint address="mex" contract="IMetadataExchange" binding="mexTcpBindng" />
    </service>
  </services>
  ...
</system.serviceModel>

使用这个配置你不应该需要code中定义的基址。

With this config you should not need to define base address in code.
