Trying to compile a XAML property that uses a generic type fails.
# Steps to reproduce
1. Open attached project in Xamarin Studio
2. Try to compile the "GenericXamlC" project
# Expected behavior
# Actual behavior
Fails to compile with error "Object reference not set to an instance of an object".
This is due to trying to set the "GenericThing" property on "MyStringControl" in GenericXamlCPage.xaml.
# Supplemental info (logs, images, videos)
Works fine with XAML compilation disabled
# Test environment (full version information)
Tested on Xamarin.Forms 22.214.171.124 and 126.96.36.199-pre5

> Object reference not set to an instance of an object.
