Xamarin seems to possibly have the best cross-platform development tools allowing the ability to reuse the same C# code across iOS, Android, Windows Phone, and Windows RT and still utilize native UI tools for each platform. I'm curious if anyone has any experience utilizing the Xamarin SDK with the ArcGIS Runtime? And if so have you had any issues or concerns with using the product?
