Xamarin introduced MonoTouch 5.2, a mobile app development platform for building iOS apps using C#. Key features included faster creation of iPhone/iPad dialogs using MonoTouch.Dialog, improved memory management tools to detect and fix leaks, and easier on-device unit testing. MonoTouch allows developers to write shorter, simpler code by harnessing C# and .NET features, and builds fully native iOS apps while reusing code across platforms. Xamarin has over 600 customers including Medtronic, JustEnough, AOL, and Monster who praise MonoTouch for reducing costs and improving quality.
