An anonymous reader cites a report on VentureBeat: Microsoft today announced that Xamarin is now available for free for every Visual Studio user. This includes all editions of Visual Studio, including the free Visual Studio Community Edition, Visual Studio Professional, and Visual Studio Enterprise. Furthermore, Xamarin Studio for OS X is being made available for free as a community edition and Visual Studio Enterprise subscribers will get access to Xamarin's enterprise capabilities at no additional cost. The company also promised to open source Xamarin's SDK, including its runtime, libraries, and command line tools, as part of the .NET Foundation 'in the coming months.' Plenty of developers will find this announcement exciting. Xamarin being free is a big deal.
