Comment 1 Joe Meirow 2015-01-31 19:36:29 UTC
I discovered that somehow my System, System.Core and System.Xml references weer all pointing to one location and my Xamarin.iOS reference was pointing to a completely different location and that these were not compatible. I deleted the reference to Xamarin.iOS and replaced with the a reference to the same name but in the location of the other DLLs and everything works now.
