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

我花了几个小时搜索这个错误，而且我已经测试了它在 Google 上的几乎所有内容.

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

我想在 C# 中使用 TCP、.NET4 和 VS2010 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);
        }

    }
}

使用此 Web.config:

With this Web.config:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.0" />

        <endpoint address="" binding="netTcpBinding" bindingConfiguration="DuplexNetTcpBinding_IService1" contract="WcfService_using_callbacks_via_tcp.IService1"/>

    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

<小时>

和托管它的代码:

---

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:
{0}:
{1}", ex.GetType(), ex.Message));
        Console.ReadLine();
    }finally
    {
        // Correct memory clean
        if(host != null)
            ((IDisposable)host).Dispose();
    }
}

<小时>

现在我想创建客户端，但我不可能.我已经直接使用了 Add Service Reference 和 svcutil，但是我收到了这个错误:

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:

套接字连接已中止.这可能是由于处理您的消息时出错或超过了接收超时远程主机，或潜在的网络资源问题.当地的套接字超时为00:04:59.9863281".

The socket connection was aborted. This could be caused by an error processi ng your message or a receive timeout being exceeded by the remote host, or an un derlying network resource issue. Local socket timeout was '00:04:59.9863281'.

如果您需要更多帮助，请输入svcutil/?"

因此，我可以毫无问题地托管服务，但无法创建代理.

---

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

我已经尝试了几乎所有找到的配置，但我认为当前的 web.config 是正确的.有端点使用的行为、安全性和使用 mex 的绑定.

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.

我尝试创建一个 app.config 并将其设置为与 svcutil.exe 相同的文件夹.

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>

使用此配置，您不需要在代码中定义基地址.

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