WCF 服务中的 C# Custom Class(server user) 在客户端不工作（但结构工作）（问题）

Question

//我的wcf服务是由控制台应用程序托管的。 console app

  using System.ServiceModel;
 using System.Text;
 using System.Threading.Tasks;

   namespace ConsoleApp1
 {
   class Program
   {
    static void Main(string[] args)
    {
        try
        {
            using (var host = new ServiceHost(typeof(ClassLibrary1.wcf_chating)))
            {

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

            }
        }
        catch (Exception ex)
        {
            
            Console.WriteLine($"Исключение: {ex.Message}");
            Console.WriteLine($"Исключение: {ex.InnerException}");
            Console.WriteLine($"Исключение: {ex.TargetSite}");
            Console.WriteLine($"Исключение: {ex.Source}");
            Console.WriteLine($"Исключение: {ex.StackTrace}");
            Console.ReadLine();
        }
    }
}
