Xamarin.Forms
So Xamarin.Forms is great, right?
Right!
And it solves all our problems?
Er, no…
Oh. But it supports native UI controls, right?
Of course
And it supports ALL native UI controls?
Um, no…
Oh. It does abstract some API interaction for us, right?
Definitely
Does it abstract ALL API interactions?
Nope
Traditional Xamarin can handle all these things
Xamarin.Forms provides mechanisms we can use to support them all from a Xamarin.Forms app
