Mono (software)
computer software project
Mono is a free and open-source software framework that aims to run software made for the .NET Framework on Linux and other operating systems. Originally by Ximian which was acquired by Novell, it was later developed by Xamarin which was acquired by Microsoft. In August 2024, Microsoft transferred ownership of Mono to WineHQ.
History
When Microsoft first announced their .NET Framework in June 2000 it was described as "a new platform based on Internet standards", and in December of that year the underlying Common Language Infrastructure was published as an open standard, "ECMA-335", opening up the potential for independent implementations. Miguel de Icaza of Ximian believed that .NET had the potential to increase programmer productivity and began investigating whether a Linux version was feasible. Recognizing that their small team could not expect to build and support a full product, they launched the Mono open-source project, on July 19, 2001, at the O'Reilly conference.
After three years of development, Mono 1.0 was released on June 30, 2004. Mono evolved from its initial focus of a developer platform for Linux desktop applications to supporting a wide range of architectures and operating systems - including embedded systems.
Novell acquired Ximian in 2003. After Novell was acquired by Attachmate in April 2011, Attachmate announced hundreds of layoffs for the Novell workforce, putting in question the future of Mono.
On May 16, 2011, Miguel de Icaza announced in his blog that Mono would continue to be supported by Xamarin, a company he founded after being laid off from Novell.
“Mono (software)” enters the record as computer software project. Crown Archives preserves that source wording while asking what Mono, software and computer can confirm, complicate or overturn.
Why this record matters
“Mono (software)” is worth following because a concise public description often conceals a longer documentary argument. Here, Mono, software and computer provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 14, 2026. The linked authority identifier is Q722656. 2 of 4 selected statements include explicit references; 2 carry qualifiers and 1 use preferred rank. The first chronological checks are 2024, 2000, 2001 and 2004.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
