Code for accesing metadata

EndpointAddress serviceEndpointAddress = new EndpointAddress("http://localhost:30617/Service1.svc/mex");

            var endpointCollection = MetadataResolver.Resolve(typeof(IService1), serviceEndpointAddress);


            foreach (var endpoint in endpointCollection)
            {
                Type bindingType = endpoint.Binding.GetType();

                if (bindingType.Equals(typeof(WSHttpBinding)))
                {
                    Console.WriteLine("Eureka!!!");
                }
            }

See if by any chance you forgot to decorate your transported classes with [DataContract] attributes (don't forget [DataMember] as well).
