In the following part of the code written in C#, we need to initialize the out-pins and manage them to control them:

using Windows.Devices.Gpio;
private void InitGPIO()
{
   var gpio = GpioController.GetDefault();
 // Show an error if there is no GPIO controller
     if (gpio == null) {
     pin = null;
    GpioStatus.Text = "There is no GPIO controller on this device.";        return;
} 
pin = gpio.OpenPin(LED_PIN);
pinValue = GpioPinValue.High;
pin.Write(pinValue); 
pin.SetDriveMode(GpioPinDriveMode.Output);
GpioStatus.Text = "GPIO pin initialized correctly.";
}
