您好Aly14，

根据代码详细信息，我发现发布元数据的问题在代码中。如果我们通过NET.TCP协议发布元数据，以及我们用于发布元数据的协议。

Hi Aly14,
According to code details, I find a problem that publishes the metadata in the code. If we publish the metadata by NET.TCP protocol, as well as the protocol we used to publish the metadata.

我做了一个演示，希望它对你有用。

I have made a demo,wish it is useful to you.

class Program
    {
        static void Main(string[] args)
        {
            var baseAddress = new Uri("net.tcp://localhost:1586/myservice");
            var binding = new NetTcpBinding();
            binding.Security.Mode = SecurityMode.Message;
            using (ServiceHost sh=new ServiceHost(typeof(MyService),baseAddress))
            {
                sh.AddServiceEndpoint(typeof(IService),binding,"");
                ServiceMetadataBehavior smb;
                smb = sh.Description.Behaviors.Find<ServiceMetadataBehavior>();
                if (smb==null)
                {
                    smb = new ServiceMetadataBehavior();
                    sh.Description.Behaviors.Add(smb);
                }
                Binding mexbinding = MetadataExchangeBindings.CreateMexTcpBinding();
                sh.AddServiceEndpoint(typeof(IMetadataExchange), mexbinding, "mex");

                sh.Open();
                Console.WriteLine("Service is ready....");

                Console.ReadLine();
                sh.Close();
            }
        }
    }

    [ServiceContract]
    public interface IService
    {
        [OperationContract]
        string SayHello();
    }
    public class MyService : IService
    {
        public string SayHello()
        {
            return "Helo Stragner";
        }
    }

结果。

如果有任何我可以帮忙的话，请随时告诉我。

Feel free to let me know if there is anything I can help with.

最诚挚的问候
