    mqttClient.ConnectedHandler = new MqttClientConnectedHandlerDelegate(OnConnected);
    mqttClient.DisconnectedHandler = new MqttClientDisconnectedHandlerDelegate(OnDisconnected);
    mqttClient.ConnectingFailedHandler = new ConnectingFailedHandlerDelegate(OnConnectingFailed);
}

private async void OnAppMessage(MqttApplicationMessageReceivedEventArgs e)
{
}

private async void OnConnected(MqttClientConnectedEventArgs e)
{
}

private async void OnDisconnected(MqttClientDisconnectedEventArgs e)
{
}

private async void OnConnectingFailed(ManagedProcessFailedEventArgs e)
{
}

Client:

• Updated async handlers:

private void Something()
{
    mqttClient.ApplicationMessageReceivedHandler = new MqttApplicationMessageReceivedHandlerDelegate(OnAppMessage);
    mqttClient.ConnectedHandler = new MqttClientConnectedHandlerDelegate(OnConnected);
    mqttClient.DisconnectedHandler = new MqttClientDisconnectedHandlerDelegate(OnDisconnected);
}

private async void OnAppMessage(MqttApplicationMessageReceivedEventArgs e)
{
}

private async void OnConnected(MqttClientConnectedEventArgs e)
{
}

private async void OnDisconnected(MqttClientDisconnectedEventArgs e)
{
}
