WS-Metadata Exchange Error
    URI: net.tcp://localhost:8000/ServiceModelSamples/service

    Metadata contains a reference that cannot be resolved: 'net.tcp://localhost:
8000/ServiceModelSamples/service'.

    There was no endpoint listening at net.tcp://localhost:8000/ServiceModelSamp
les/service that could accept the message. This is often caused by an incorrect
address or SOAP action. See InnerException, if present, for more details.

If you would like more help, type "svcutil /?"

Here is the code i wrote in Host application

    class Program
    {
        static void Main(string[] args)
        {
            Uri baseAddress = new Uri("net.tcp://localhost:8000/ServiceModelSamples/Service");
            ServiceHost serviceHost = new ServiceHost(typeof(CalculatorService), baseAddress);
            try
            {
                // Add a service endpoint
                serviceHost.AddServiceEndpoint((typeof(ICalculator)) ,new  NetTcpBinding ()   ,  "CalculatorService");
                // Enable metadata exchange
                ServiceMetadataBehavior smb = new ServiceMetadataBehavior();
                //smb.HttpGetUrl = new Uri("http://localhost:8000/ServiceModelSamples/Service"); ;
                serviceHost.Description.Behaviors.Add(smb);
                serviceHost.Open();
                Console.WriteLine("The service is ready.");
                Console.WriteLine("Press <ENTER> to terminate service.");
                Console.WriteLine();
                Console.ReadLine();

                // Close the ServiceHostBase to shutdown the service.
                serviceHost.Close();
            }
            catch (CommunicationException ce)
            {
                Console.WriteLine("An exception occured: {0}", ce.Message);
                serviceHost.Abort();
            }
        }
    }

Can you tell me where i am going wrong?
