When the Raspberry Pi application does not require a display screen or monitor, it is helpful if the LED is blinking to show that OS is started up and ready for use.
This is also an example of IoT core background application. Very easy level of programming.
Everything is based on the first BlinkyLED example of Windows IoT core. I am using Task.Delay instead of TimeDispatcher. I am looking for optimizing it for less resources and processes, so if you have any ideas, I am happy to listen.
