Please help: Error with zero application (non-infrastructure) endpoints.

Question

I've very new to using WCF.  I've been following a number of tutorials, but try as I might I keep getting stuck on the same error. 

"Service 'CoreSiX.Implementation.SiXAdmin' has zero application (non-infrastructure) endpoints. This might be because no configuration file was found for your application, or because no service element matching the service name could be found in the configuration file, or because no endpoints were defined in the service element."

I'm guessing this is down to my configuration but I'm unsure exactly what's wrong.  I've listed the code below.  Any canone give me any pointers?

      public ServiceHost host = null;
      public CoreSiXService() {
         ServiceName = "CoreSiX_Service";
      }
 
      public static void Main(){
         System.Diagnostics.Debugger.Launch(); 
         ServiceBase.Run(new CoreSiXService());
      }
 
      protected override void OnStart(string[] args){
         if (host != null)
            host.Close();
         host = new ServiceHost(typeof(SiXAdmin));
         host.Open();
      }

 
      protected override void OnStop(){
         if (host != null){
            host.Close();
            host = null;
         }
      } 
   }

   public class CoreSiXServiceInstaller : Installer {
      private ServiceProcessInstaller process;
      private ServiceInstaller service;
 
      public CoreSiXServiceInstaller() {
         process=new ServiceProcessInstaller();
         process.Account=ServiceAccount.LocalSystem;
         service=new ServiceInstaller();
         service.ServiceName="CoreSiX_Service";
         Installers.Add(process);
         Installers.Add(service);
