Xamarin Cross-Plataform MvvM pattern
I did this model through the following tutorial:
NinjaTips | Xamarin Fomrs: Creando una app desde cero https://www.youtube.com/watch?v=mJ7TIXUJmIs
It's basically a testing of navigation properties through XAML pages using a main menu and MVVM model. I will yet implement the database using SQLLite. Haven't done it yet, because the tutorial goes along with Azure, and I don't have any Azure account.
