Xamarin, makers of cross-platform frameworks for building mobile applications, today announced a $12 million round of funding from Charles River Ventures, Ignition Partners and Floodgate. This is the first round of funding for Xamarin, which develops Mono, an open source project that brings Microsoft’s .NET development framework to non-Microsoft operating systems like Android, iOS and Linux.

Just two weeks later de Icaza announced Xamarin.
Although Mono is free and open source, Xamarin makes money by selling enterprise licenses and support for MonoTouch (an implementation of .NET for iOS) and Mono for Android. In July 2011 Novell granted Xamarin a perpetual license for both products, which let Xamarin avoid having to rebuild the products from scratch.

Xamarin is composed of more than 20 members of the team that built Mono - the open source, cross-platform implementation of C# and the .NET framework, with ten years of experience working together to create a great developer platform. Xamarin’s Mono-based products enable .NET developers to use their existing code, libraries and tools (including Visual...
