Insert a RadialProgressView in a ContentPage

Hi Community!

I'm having newbie's trouble trying to integrate the RadialProgress, from Xamarin Components, into a ContentPage of my Xamarin Forms project. It works fine as an activity, just like in the samples, but the "RadialProgressView" can't seem to be called as a Xamarin.Forms View. Would you have the kindness to guide me toward tutorials, samples or references that could lead me to how I can integrate a RadialProgress the way I do with, say, an ActivityIndicator?

Sincerely,
Julien
