The fix..(thank you Kym Phillpotts)

  1. It would appear, that the added pages have the wrong namespace. So change the namespace on the added pages
  • Page1.xaml.cs - change the Namespace to be just MyApp
  • Page1Detail.xaml.cs - Change the namespace to be just MyApp
  • Page1Master.xaml.cs - Change the namespace to be just MyApp
  • Page1MenuItem.cs - Change the namespace to "MyApp"
  1. I also noticed that in the Page1Master.xaml.cs it is incorrectly referencing the MenuItems. It says Page1MenuItems = new ObservableCollection...Change that to be justMenuItems = new ObservableCollection...

No you can go to your App.Xaml.xs and set the Page1 as the master page:

eg.MainPage = new MyApp.Page1()
