As we reported earlier, Microsoft announced that they finally acquired Xamarin. The deal was announced on Wednesday by both companies without revealing terms of the deal. Now according to Bloomberg, Microsoft will pay about $400 million for software developer tools startup Xamarin, according to people with knowledge of the agreement.

Scott Guthrie, Microsoft’s executive vice president wrote Wednesday in a blog post:

“The acquisition is the tech giant’s latest move to attract more software engineers to write programs using its cloud services. Integrating San Francisco-based Xamarin into Microsoft’s Visual Studio will improve developers’ ability to build mobile applications across Apple Inc.’s iOS, Google’s Android and Microsoft’s Windows by making it easier to share code among the different operating systems”.
