I have made a "small" update on my MQTT client (now at version, adding an additional constructor on MqttClient class which has the host name of the broker as parameter (adding to the constructor that provides only the address IP). Such a constructor may be useful in all those cases in which you use a MQTT public broker , such as the Mosquitto test server that is at test.mosquitto.org.

   1: public static void Main()
   2: {
   3:     MqttClient client = new MqttClient("test.mosquitto.org");
   4:     ...
   5:     ...
   6: }
