Xamarin was a cross-platform mobile development framework company founded in 2011 by the creators of Mono, an open-source implementation of Microsoft’s .NET Framework; Microsoft announced its acquisition of Xamarin on 24 February 2016[1]. The technology and its community were subsequently folded into Microsoft’s developer tooling, including Visual Studio and later .NET MAUI. Xamarin’s associated visual mark has appeared in many third-party logo collections, but Logo Index’s cited sources do not document its designer, date of introduction, or design rationale, so those details are not included here. Logo Index presents this entry as an archived mark connected to the Xamarin entity, without asserting unverified visual or historical claims.
Logo Index is an independent educational archive covering logos, visual identities and graphic design history. All trademarks and brand assets remain the property of their respective owners.
