            var client = new FabricClient(new string[] { "[cluster_endpoint]:[client_port]" });

            var filter = new ServiceNotificationFilterDescription()
            {
                Name = new Uri("fabric:/my_application"),
                MatchNamePrefix = true,
            };

            client.ServiceManager.ServiceNotificationFilterMatched += (s, e) => OnNotification(e);

            var filterId = client.ServiceManager.RegisterServiceNotificationFilterAsync(filter).Result;

            Console.WriteLine(
                "Registered filter: name={0} id={1}",
                filter.Name,
                filterId);

            Console.ReadLine();

            client.ServiceManager.UnregisterServiceNotificationFilterAsync(filterId).Wait();
