Run WCF ServiceHost with multiple contracts

Question

Running a ServiceHost with a single contract is working fine like this:

servicehost = new ServiceHost(typeof(MyService1));
servicehost.AddServiceEndpoint(typ

I'm currently faced with the same problem, and have decided to go with the implementation below. I'm not sure if there are any performance issues with having this many service contracts, but in my final implementation I will probably have about 10 - 15 service contracts, thus about 10-15 ServiceHosts.

I am hosting all my WCF services inside a single Windows Service.

private void PublishWcfEndpoints()
{
    var mappings = new Dictionary
    {
       {typeof (IAuthenticationService), typeof (AuthenticationService)},
       {typeof(IUserService), typeof(UserService)},
       {typeof(IClientService), typeof(ClientService)}
    };


    foreach (var type in mappings)
    {
        Type contractType = type.Key;
        Type implementationType = type.Value;

        ServiceHost serviceHost = new ServiceHost(implementationType);
        ServiceEndpoint endpoint = serviceHost.AddServiceEndpoint(contractType, ServiceHelper.GetDefaultBinding(),
                                                                  Properties.Settings.Default.ServiceUrl  + "/" + contractType.Name);
        endpoint.Behaviors.Add(new ServerSessionBehavior());

        ServiceDebugBehavior serviceDebugBehaviour =
            serviceHost.Description.Behaviors.Find();
        serviceDebugBehaviour.IncludeExceptionDetailInFaults = true;

        log.DebugFormat("Published Service endpoint: {0}", Properties.Settings.Default.ServiceUrl);

        serviceHost.Open();
        serviceHosts.Add(serviceHost);
    }

}

Feel free to comment on this type of set up, and if there are any issues with it, especially performance-related.
