FragmentPagerAdapter Exists Only In Android.Support.V4.App (and not Android.App)
...
Ugh, you just need to use the FragmentPagerAdapter from the V13 support library

How can I return NULL from a generic method in C#?
...that if you're using this generic method to say, convert a Database object from DbNull to Int and it returns default(T) where T is an int, it'll return 0. If this number is actually meaningful, then you'd be passing around bad data in cases where that field was null. Or a better example would be a D...
