A compiler and toolchain that lets you write native apps for iOS, Mac, Android, Windows and Windows Phone in C#. RemObjects C# isn't a .NET bridge, but instead provides direct access to each platform's native APIs. The RemObjects C# language provides access to all Cocoa, Cocoa Touch and the Objective-C Runtime frameworks including external open source and third party libraries and compiles to a fully native executable for the Objective-C runtime.
