THE company which former Microsofters are funding, Xamarin, is still openwashing and enhancing Microsoft products. Open Source-centric Web sites fall into the trap of covering proprietary as though it is "open" and to quote this one example:
Xamarin has announced an across-the-board update to its range of products and pricing models designed to establish the company as the de facto bridge between Microsoft C# developers and Android and iOS mobile platforms. Xamarin's speciality has been working with the Mono toolchain for C# and for mobile development; rather than abstract away platform differences, the company implements a close-as-possible version of the platform's native APIs in C#.
Since 2009, it's been possible to develop iOS applications using C# and .NET, courtesy of MonoTouch. But one important detail has always been missing. If you wanted to use Visual Studio—the premier C# and .NET development environment, the one that almost every C# developer calls home—you were out of luck.
