Error initializing a new XAML Page

Hey guys!

So after a bit of study I decided to test a simple application from Xamarin Studio, so I made 4 XAML pages and tried to run the app in the emulator. The problem is I always get the following exception in the page's constructor, the InitializeComponent() call:

java.lang.reflect.InvocationTargetException

I tried changing the page thinking It could be something wrong but I still get the same exception. Any ideas or suggestions ?

Thank you!
