StanConnection will not reconnect after losing connection to server and rosolving it again in version 0.3.0

[shokri-navid]

I create a simple stan client with the below code by stan client 0.3.0:

      static void Main(string[] args)
        { 
           var cf = new ConnectionFactory();
            var sf = new StanConnectionFactory();
            var natsConnection = cf.CreateConnection(GetOpts());

            var stanOpts = StanOptions.GetDefaultOptions();
            stanOpts.ConnectTimeout = 4000;
            stanOpts.NatsConn = natsConnection;
            stanOpts.PubAckWait = 40000;
            //stanOpts.

            var stanConnection = sf.CreateConnection("test-cluster", "uniq123", stanOpts);
            var watch = Stopwatch.StartNew();

            while (true)
            {
                try
                {
                    stanConnection.Publish("test", new byte[0x1]);
                    Console.WriteLine("{0}. Published message", watch.Elapsed);
                }
                catch (Exception e)
                {
                    Console.WriteLine("{0} - Type:{1}. On Publish: exception message: {2}", watch.Elapsed, e.GetType(), e.Message);
                }
                finally
                {
                    Thread.Sleep(1000);
                }
            }
        }
        
        private static Options GetOpts()
        {
            var opts = ConnectionFactory.GetDefaultOptions();
            opts.Url = "nats://localhost:4222";
            opts.AllowReconnect = true;
            opts.PingInterval = 5000;
            opts.MaxPingsOut = 2;
            opts.MaxReconnect = Options.ReconnectForever;
            opts.ReconnectWait = 1000;
            opts.Timeout = 4000;

            opts.ServerDiscoveredEventHandler += (sender, args) => Console.WriteLine("NATS server discovered");

            opts.ReconnectedEventHandler +=
                (sender, args) =>  Console.WriteLine( "NATS server reconnected.");
            opts.ClosedEventHandler +=
                (sender, args) => Console.WriteLine("NATS connection closed");
            opts.DisconnectedEventHandler += (sender, args) =>
                Console.WriteLine("NATS connection disconnected");
            opts.AsyncErrorEventHandler +=
                (sender, args) => Console.WriteLine("NATS async error: {0}, Message={1}, Subject={2}", args.Conn.ConnectedUrl,
                    args.Error, args.Subscription.Subject);

            return opts;
        }

and host the latest version NatsStreaming with docker on my machine. when I run my client it connects to the server and publishes its messages. when I stop my NatsStreaming service and start it again the nats connection reconnects to the server but StanClient still is throwing connection closed Exception. this issue removes if I downgrade my client version to 0.1.14.

Update

I resolve the problem by setting
StanOptions.NatsConnection = arg.Conn
inside reconnect Handler but I wonder why it needs such unusual action like this?
I add another sample on Issue #162
