In February 2013, Xamarin announced the release of Xamarin 2.0. In December 2012, Xamarin released Xamarin.Mac, a plugin for the existing MonoDevelop Integrated development environment (IDE), which allows developers to build C#-based applications for the Apple's macOS operating system and package them for publishing via the App Store. In July 2011, however, Novell – now a subsidiary of Attachmate – and Xamarin announced that Novell had granted a perpetual license to Xamarin for Mono, MonoTouch and Mono for Android, and Xamarin formally and legally took official stewardship of the project.

It was not known at that time how Xamarin would prove they had not illegally used technologies previously developed when they were employed by Novell for the same work. Īfter Xamarin was announced, the future of the project was questioned since MonoTouch and Mono for Android would now be in direct competition with the existing commercial offerings owned by Attachmate. This is in line with the naming theme used ever since Ximian was started. The name Xamarin comes from the name of the Tamarin monkey, replacing the leading T with an X. According to de Icaza, at least part of the original Mono team had moved to the new company. On May 16, 2011, Miguel de Icaza announced on his blog that Mono would be developed and supported by Xamarin, a newly formed company that planned to release a new suite of mobile products. Īfter the acquisition, Attachmate announced hundreds of layoffs for the Novell workforce, including Mono developers, putting the future of Mono in question. Ximian was bought by Novell on August 4, 2003, which was then acquired by Attachmate in April 2011. The Mono open source project was launched on July 19, 2001. NET Framework in June 2000, de Icaza began investigating whether a Linux version was feasible. In 1999 Miguel de Icaza and Nat Friedman launched what eventually became known as Ximian to support and develop software for de Icaza's nascent GNOME project.
