Best practice to put GPIO logic in UWP

Question

If I create a app in UWP for example with Template 10. I use C#

I want to have the GpioController logic in a class or somewhere that will handle all input and output business like set all pins and events.

Like an example, when a button is pressed it will send a POST request to the server, this must work in any view.

If I go to a view and I want to get the status of a pin to show like "The door is open"

Also if for an example a sensor is triggering a pin to HIGH, if i change view it cant trigger buttonPin_ValueChanged event and or set it to LOW for any reason unless the sensor is LOW.

Even if the pins Power-on Pull is PullDown.

pin = gpio.OpenPin(12);
pin.SetDriveMode(GpioPinDriveMode.InputPullUp);
pin.Write(GpioPinValue.Low);
pin.ValueChanged += buttonPin_ValueChanged;

You can create a GpioController object in your initial class, and pass it as an object to other classes.

Such as:

class BaseClass {
    GpioController gpio;

    void createGpioController(){
        gpio = new GpioController(/*Constuctor arguments here.*/);
    }

    void moveToNextClass(NextClass next){
        //Instantiate next class with any special constructors.
        next.gpio = this.gpio; 
        //Launch next class with same gpio member values. 
    }
}

class NextClass: BaseClass {
   GpioController gpio; //Will be assigned by last class.
}
