System.TypeInitializationException when running on iPhone simulator

[sundraw]

The exception occurred when running a Xamarin.Forms app on iOS (both simulator and device). The same code runs just fine on an Android emulator.

Here is the stack trace. It looks like the reason for the problem is the use of 1252 encoding.

I just find this : http://developer.xamarin.com/guides/ios/advanced_topics/localization_and_internationalization/encodings/

Did you activate the "west" extra encoding ?

Wonderful! Now it works.
