We are using Xamarin.iOS unified API and hitting this same issue:
http://stackoverflow.com/questions/28210124/mvvmlight-and-xamarin-unified-api-property-not-found
However, we are trying to do a viewmodel -> controller binding (basically OneWayToSource in WPF world) and since the Property Not Found exception is being hit on the VM property we are not able to use the workaround mentioned in that stack overflow. For now, we are listening to the "PropertyChanged" event in our iOS controller and changing the property after checking the PropertyEvent property of the event args. We would like to avoid this so hopefully a fix can be put in soon.
For tracking this down, I tried to see if it was a Xamarin runtime reflection issue by stepping through getting the type and looking up by property name and that worked. That was not in the Extension method itself though, for some reason whenever I try to download the source code from Codeplex the iOS platform helpers folder is missing all the binding files, including extensions.
Let me know anything else I can provide to help trace this down. Thanks!
