Windows 8.1 Phone App does not show Pages

[apacha]

I've tried to run the sample applications. I'm especially interested in the Windows 8.1 and Windows 8.1 Phone projects. The Windows 8.1 project works fine, but when starting the Windows 8.1 Phone project in an emulator, all I see is the following:

I needed to update some referenced libraries in order to run it. The repository that contains the changes can be found here.

I've been debugging the application and all steps (Setup, Forms.Init, etc.) seems to run fine. I just wanted to check, if anyone can reproduce this behaviour, or if it is just my computer that is making troubles. And if so, does anybody know why this is happening? What is wrong? Any help is appreciated.

Steps to reproduce

1. Check out Repository
2. Open Project Samples / Example001XAML
3. Set Windows Phone 8.1 Silverlight as Startup Project and start Debugging in any Emulator
