WCF/WF - net tcp multiple address points - Asked By karur krishna madhu on 04-Mar-14 04:22 AM

There is already a listener on IP endpoint 0.0.0.0:8099.  Make sure that you are not trying to use this endpoint multiple times in your application and that there are no other applications listening on this endpoint

i have mentioned this end point as the base address in the wcf service library config file and i have mentioned the same thing in the console host app.config file 

 var nettcpservicehst = new ServiceHost(typeof(WcfServiceContract.DivideService));
            nettcpservicehst.Open();
            Console.WriteLine("Nettcp service host is up");
            Console.ReadLine();
            nettcpservicehst.Close();

i get the error

i have checked that this end point 8099 is not used for any other apps in my local system. but still i get the same error . how to fix this?
