XAML examples functional?

I'm trying to get started with Xamarin.Forms, specifically with creating individual pages using xaml instead of code.

1. Created an example project using the universal forms prototype
2. Created a XAML forms page, again using the appropriate prototype
3. Compiling gives an error in my example.xaml.cs page that InitializeComponent is undefined.

What are the bare minimum steps necessary to create a Hello World Xamarin.Forms application using XAML for page creation?
