title: Where to get HELLO WORLD for .net with M2mQTT
body: <p>Start working on <strong>MQTT</strong> with <strong>.net</strong> environment, as a novice stuck on some issues like failed to communicate between publisher and SUBSCRIBER. From <strong><a href="https://eclipse.org/paho/clients/dotnet/" rel="nofollow">eclipse.org</a></strong> I get the bellow syntax</p>
  
  <pre><code>// SUBSCRIBER
  ...
  
  // create client instance
  MqttClient client = new MqttClient(IPAddress.Parse(MQTT_BROKER_ADDRESS));
  
  // register to message received
  client.MqttMsgPublishReceived += client_MqttMsgPublishReceived;
  
  string clientId = Guid.NewGuid().ToString();
  client.Connect(clientId);
  
  // subscribe to the topic "/home/temperature" with QoS 2
  client.Subscribe(new string[] { "/home/temperature" }, new byte[] { MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE });
  
  ...
  
  
  static void client_MqttMsgPublishReceived(object sender, MqttMsgPublishEventArgs e)
  {
  // handle message received
  }
  
  // PUBLISHER
  ... 
  
  // create client instance
  MqttClient client = new MqttClient(IPAddress.Parse(MQTT_BROKER_ADDRESS)); 
  
  string clientId = Guid.NewGuid().ToString();
  client.Connect(clientId); 
  
  string strValue = Convert.ToString(value); 
  
  // publish a message on "/home/temperature" topic with QoS 2
  client.Publish("/home/temperature", Encoding.UTF8.GetBytes(strValue), MqttMsgBase.QOS_LEVEL_EXACTLY_ONCE); 
  
  ...
  </code></pre>
  
  <p>In the above syntax how I get the <strong>MQTT_BROKER_ADDRESS</strong> ,  so far I understood from other document like <a href="http://www.hivemq.com/blog/mqtt-client-library-encyclopedia-m2mqtt" rel="nofollow">hivemq</a>  I need to deploy it. Is there any broker available to use it? I need a <strong>HELLO WORLD</strong> type project on MQTT for .net.
  Which have publisher,subscriber and broker.</p>
