Host multiple contracts in one CoreWCF service

[DarioSalcedo]

Is it possible to host multiple service contracts in one CoreWCF service? If so, how? I've been googling and some posts say you can do it (but not how)

Code: CoreWCF_TestMultipleContracts.zip

I'm trying not to have one interface with N methods in it. And I don't want to have to host X different WCF services to do this. Please, I humbly request your support :)

  public void ConfigureServices(IServiceCollection services)
        {
            services.AddServiceModelServices();
        }
        public void Configure(IApplicationBuilder app)
        {
            NetTcpBinding netTcpBinding = new NetTcpBinding
            {
                TransferMode = TransferMode.Streamed
            };
            if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
                netTcpBinding.Security.Mode = SecurityMode.None;
            else
            {
                netTcpBinding.Security.Mode = SecurityMode.Transport;
                netTcpBinding.Security.Transport.ClientCredentialType = TcpClientCredentialType.Windows;
            }

            app.UseServiceModel(builder =>
            {
                builder.AddService<ServiceCaja>();
                builder.AddServiceEndpoint<ServiceCaja, Contracts.IServiceCaja>(netTcpBinding, "/ServiceCaja");

                builder.AddService<ServiceCategoria>();
                builder.AddServiceEndpoint<ServiceCategoria, Contracts.IServiceCategoria>(netTcpBinding, "/ServiceCategoria");
            });
        }

In Program:

 static void Main(string[] args)
        {
            int port = 11808;
            IWebHost host = CreateWebHostBuilder<Startup>(IPAddress.Loopback, port).Build();
            host.Run();
        }
     public static IWebHostBuilder CreateWebHostBuilder<TStartup>(IPAddress? ipAddress = null, int port = 0) where TStartup : class
        {
            if (ipAddress == null)
                ipAddress = IPAddress.Loopback;

            IWebHostBuilder builder = WebHost.CreateDefaultBuilder(Array.Empty<string>())
                .UseNetTcp(ipAddress, port)
                .UseStartup<TStartup>();

            return builder;
        }        

In the Client solution, only the first call is recognized.

    static void Main(string[] args)
        {
            NetTcpBinding netTcpBinding = new NetTcpBinding
            {
                TransferMode = TransferMode.Streamed
            };

            int port = 11808;
            string expectedBaseAddress = $"net.tcp://{IPAddress.Loopback}:{port}";

            var factory = new System.ServiceModel.ChannelFactory<Server.Contracts.IServiceCaja>(netTcpBinding,
                new System.ServiceModel.EndpointAddress(new Uri($"{expectedBaseAddress}/ServiceCaja")));
            var channel = factory.CreateChannel();
            var result = channel.ListarCajas();

ERROR HERE CALL

            var factory1 = new System.ServiceModel.ChannelFactory<Server.Contracts.IServiceCategoria>(netTcpBinding,
                new System.ServiceModel.EndpointAddress(new Uri($"{expectedBaseAddress}/ServiceCategoria")));
            var channel1 = factory1.CreateChannel();
            var result1 = channel1.ListarCategorias();

            Console.ReadLine();
        }
