True, but it means taking the rest of Xamarin, too. While Xamarin is brilliant, and by far the best cross-platform SDK I've seen for any set of targets, it's still riskier than native platform development for most developers. I'd use it for a client who has a C#-oriented in-house team and the ability and resources to commit to overcoming the vicissitudes of cross-platform development, but I wouldn't just to get LINQ.
