Unable to open its IChannelListener RRS feed

  • Question

  • Hi everyone,

    I'm trying to make a simple WCF application with client authentication.

    I've found this

    But I want it to be progammatical, so, I've done this code :

    private static void Main(string[] args)
                //const string serviceAddress = "http://localhost:27020/AccountAuthenticator";
                var serverPort = 0;
                while (true)
                        Console.Write("Enter service port : ");
                        serverPort = int.Parse(Console.ReadLine());
                    catch (Exception)
                        Console.WriteLine("Invalid server port. Please try again");
                var serviceAddress = string.Format("http://localhost:{0}/AccountAuthenticator", serverPort);
                // Create an isntance of service host which manages connection from clients.
                var serviceHost = new ServiceHost(typeof (AuthenticationService), new Uri(serviceAddress));
                // Create an instance of ServiceMetadataBehavior class to define what server will behave.
                var serviceMetadataBehavior = new ServiceMetadataBehavior();
                var serviceCredentials = new ServiceCredentials();
                serviceCredentials.UserNameAuthentication.UserNamePasswordValidationMode = UserNamePasswordValidationMode.Custom;
                serviceCredentials.UserNameAuthentication.CustomUserNamePasswordValidator = new IdentityValidator();
                serviceHost.AddServiceEndpoint(typeof (IMetadataExchange), MetadataExchangeBindings.CreateMexHttpBinding(),
                // Create an instance of BasicHttpBinding with default initialization.
                var wsDualHttpBinding = new WSDualHttpBinding();
                wsDualHttpBinding.Security.Mode = WSDualHttpSecurityMode.Message;
                wsDualHttpBinding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
                serviceHost.AddServiceEndpoint(typeof (IAuthenticationService), wsDualHttpBinding, serviceAddress);
                Console.WriteLine("Service has started at port {0}. Press enter to terminate", serverPort);

    But it gave me an error when I tried to open the service.

    The ChannelDispatcher at 'http://localhost:27515/AccountAuthenticator' with contract(s) '"IAuthenticationService"' is unable to open its IChannelListener.

    Can anyone help me , please ?

    Thank you.

  • Hi Linh Nguyen Duy,

    According to this case, as far as I know, when we used username and password, we need

    to use the certificate to encrypt  the username and password. So, we need to set the

    certificate with server-side.

    We need to create a certificate, then add the following code to server-side.

    serviceHost.Credentials.ServiceCertificate.SetCertificate(StoreLocation.LocalMachine, StoreName.My, X509FindType.FindBySubjectName, "localhost");

    For more information, please refer to the following articles:
