I realize that this is found here: forums.xamarin.com/discussion/2136/is-it-possible-to-call-xamarin-code-from-an-androidiphonewp7-native-app, however the thread appears to be dormant.
In short, I am curious about the 'status' of building 'cross-platform' libraries in Xamarin that can be included in Android and iOS native code. This would be a 'killer' feature for us, but it appears from the thread above that it was not supported earlier this year. I am curious if there is any change?
