UWP app with restful GET : I am very new to C# but I need to write an UWP app to run on a Raspberry Pi with Windows 10 IoT.

I have a bluetooth dongle connected to the Pi, the app needs to send an On-Command to a Philipps Hue Ligthscrip with a restful GET when the button is pressed.

I've tried to Google myself through Stack Overflow, Microsoft's repositories and thousands of other sites, no luck. There must be something possible with HttpClient (https://docs.microsoft.com/en-us/windows/uwp/networking/httpclient) but I could not figure out how to send GET...

Thanks
