how to send a signal to run a machine using netdui

Question

first, i am a beginner in Netduino and micro-framework, so this is my situation : i have an application (winforms app) in a Win Pad this application it for sleeping detection, and i have a Netduino cart, what i want it's send a signal(start/stop) from my Netduino to the car window, that mean if the signal is sent the window is coming down and if it's sent for the second time the window is coming up. i am already see an example of LED :

  public static void Main()
    {
    var led = new OutputPort(Pins.GPIO_PIN_D0, false);

    while (true)
    {
        led.Write(!led.Read());
        Thread.Sleep(1000);
    }
    }

so please if someone has any idea i will be very appreciative.

Update : this is my code it very basic and i wondered if it's correct.

        OutputPort CarWindow = new OutputPort(Pins.GPIO_PIN_A0, false);
        while (true)
        {
            CarWindow.Write(true);//open the window
            Thread.Sleep(2000);

        }
