The amount of the deal, whose closing is still subject to regulatory approval, was not disclosed.
The acquisition will enable Microsoft to combine Xamarin with Visual Studio, Visual Studio Team Services, and Azure to provide a complete mobile app dev solution that provides everything developers need to develop, test, deliver and instrument mobile apps for every device.
Founded in 2011, Xamarin provides a mobile development platform that enables developers to build mobile apps using C# and deliver fully native mobile app experiences to all major devices – including iOS, Android, and Windows. Its approach enables developers to use .NET to build mobile apps, and C# to write to the full set of native APIs and mobile capabilities provided by each device platform.
The company, which employs more than 350 people in 15 countries including in its offices in San Francisco, Boston, London, Århus, and Buenos Aires, among others, has more than 15,000 customers including Alaska Airlines, Coca-Cola Bottling, Thermo Fisher, Honeywell JetBlue, SuperGiant Games and Gummy Drop.
Xamarin was backed by Charles River Ventures, Floodgate, Ignition Partners, Insight Venture Partners, and Lead Edge Capital.
