Possible to have same contract, same binding, same address, but different ports?

I have handhelds that need to communicate via basicHTTPBinding. I have a contract and everything works as advertised.

I need to expand it to easily support changing to a test environment, training and of course production. I took the port route, thinking I could expose different endpoints with port differences, and based on the port, decide which database I wanted info from.

I cant seem to make thi开发者_如何学编程s work, and so far have found no information anywhere that indicates it can be done. Since port is optional, it may not be.

Anyone done anything like this?

Although you can't do what you want with the port you can accomplish this with a different path. Such as appending "/prod" or "/test" to your base address. I've included an example that illustrates this.

using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ServiceModel;
using System.ServiceModel.Description;

namespace WCFTest
{
    class Program
    {
        static void Main()
        {
            List<Uri> baseAddresses = new List<Uri> { new Uri("http://localhost:1000/Prod"), new Uri("http://localhost:1000/Test") };
            ServiceHost wcfHost = new ServiceHost(typeof(SimpleWCF), new Uri[] {new Uri("http://localhost:1000")});

            foreach (ServiceEndpoint endpoint in SimpleWCF.CreateEndpoints(baseAddresses.ToArray()))
            {
                wcfHost.AddServiceEndpoint(endpoint);
            }

            ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior();
            metadataBehavior.HttpGetEnabled = true;
            wcfHost.Description.Behaviors.Add(metadataBehavior);

            wcfHost.Open();
            Console.ReadLine();
            wcfHost.Close();
        }
    }

    [ServiceContract]
    public interface ISimpleWCF
    {
        [OperationContract]
