MVVM Pattern without XAML and Fody in Xamarin?

Hello everyone,

i would like to know about MVVM pattern without XAML, i dont feel corfortable using XAML, so you guys have experience with MVVM without XAML?

i found only this tutorial: https://github.com/MvvmCross/MvvmCross-Forms

in MVVMCross they have an example without XAML but is like strange...

another problem is about INotifyPropertyChanged i have to do this for each property:

string familyName;
    public string FamilyName
    {
        get { return familyName; }
        set 
        {
            if (value != familyName)
            {
                familyName = value;
                OnPropertyChanged("FamilyName");
                OnPropertyChanged("FullName");
            }
        }
    }

there are another simple way and clean? someone know how to use this: https://github.com/Fody/PropertyChanged
or another easy way?

i am open to ideas and personal experience, thank you all
