<h2 id="download">Download</h2>
<p>The M2Mqtt client assemblies for using as references in your Visual Studio projects can be downloaded from <a href="https://www.eclipse.org/downloads/download.php?file=/paho/1.2-milestones/m2mqtt/M2Mqtt_4.2.0.0.zip">here</a></p>

<h2 id="build-from-source">Building from source</h2>
<p>The project can be installed from the repository as well. To do this:</p>
<pre>git clone https://github.com/eclipse/paho.mqtt.m2mqtt.git</pre>
<p>You can open one of the available solutions for Visual Studio (in the "org.eclipse.paho.mqtt.m2mqtt" folder) depends on .Net or WinRT platform you want to use.</p>

<h3 id="getting-started">Getting Started</h3>
<p>Here is a very simple example that shows a publisher and a subscriber for a topic on temperature sensor:</p>
<pre>
// 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);

...
