it seems introduce code parse before compiler time. it's possible in android (jit just-in compiler time) not ios (aot ahead of time). read xamarin wrote in page http://docs.xamarin.com/guides/ios/advanced_topics/limitations/

since iphone's kernel prevents application generating code dynamically mono on iphone not support form of dynamic code generation.

hope help!
