Device.OS is Obsolete in Xamarin.Forms... What to do?!?!

If you just updated to Xamarin.Forms 2.3.4 you may have noticed and be freaking out that you have tons of green squiggles that Device.OS and TargetPlatform are obsolete. This was all done in regards to the new changes for OnPlatform.

Don’t be scared as it is an easy fix as Device now includes constant values for each platform. Just replace your TargetPlatform with Device and you are basically done:

Device now contains:

How about TargetIdiom?!?!? Well that is still there and not obsolete lols. I assume eventually there will be a RuntimeIdiom, who knows.
