### Overview
In some apps using the new FormsAppCompatActivity in Forms 2.0, rotating the device’s screen causes a crash with the stack trace:

Comment 2 Jimmy [MSFT] 2015-12-15 18:40:10 UTC
The Main activity class was missing "ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation" in it's declaration.
