In order to support 64-bit iOS and OSX, Xamarin has to make some breaking changes to the way it implements the mapping between C# and Objective-C libraries. Rather than being mapped to 32-bit types, NSInteger and CGFloat are now mapped to the new platform-specific data types nint and nfloat.
Xamarin has released a preview of their async-enabled libraries for iOS and Android development. This work is based heavily on Microsoft’s .NET 4.5, which was released late last year as part of Visual Studio 2012. Xamarin is the new name for the development platforms previously known as MonoTouch and Mono for Android.
Xamarin, makers of the popular MonoTouch and Mono for Android platforms, have entered into the Mac App Store market with Xamarin.Mac.
The MonoDevelop team has just released version 2.8 of their open-source for IDE for .NET and Mono development. InfoQ took a moment to speak with MonoDevelop's project manager Lluis Sanchez to discuss this release and its increasing popularity on Mac and Windows.
Novell Mono is officially dead. All of the developers have been let go and the new owner, Attachmate, has not expressed any interest in maintaining the project. But in true open source fashion, a new fork is rising up. Led by Mono’s founder Miguel de Icaza, a new company named Xamarin has been founded.
MonoMac, the newest attempt at creating a GUI toolkit for C# on OS X, has hit its 1.0 release. MonoMac is designed to be much more consistent with other .NET/Mono libraries. This is done by offering a thicker wrapper around the Cocoa APIs that obeys the .NET Framework Design Guidelines.
