WCF服務中的C＃自定義類（服務器用戶）在客戶端中不起作用（但結構作業）（問題）-有解無憂

//我有 wcf 服務由控制臺應用程式托管。控制臺應用

 using System.Threading.Tasks;

            using (var host = new ServiceHost(typeof(ClassLibrary1.wcf_chating)))
            {

                host.Open();
                Console.WriteLine("Стартуем!");
                Console.ReadLine();

            }
