Xamarin is a Microsoft-owned San Francisco, California based software company founded in May 2011[3] by the engineers that created Mono,[4] Mono for Android and MonoTouch that are cross-platform implementations of the Common Language Infrastructure (CLI) and Common Language Specifications (often called Microsoft .NET).

With a C#-shared codebase, developers can use Xamarin tools to write native Android, iOS, and Windows apps with native user interfaces and share code across multiple platforms.[5] Over 1 million developers use Xamarin's products in more than 120 countries around the world as of May 2015.[6]

On February 24, 2016, Microsoft announced it signed a definitive agreement to acquire Xamarin.[7]

History

Ximian Founding and Acquisition

In June 2000, Microsoft first announced their .NET Framework.[8] Miguel de Icaza of Ximian began investigating whether a Linux version was feasible.[9] The Mono open source project was launched on July 19, 2001. Ximian was bought by Novell on August 4, 2003, which was then acquired by Attachmate in April 2011.[10]

After the acquisition, Attachmate announced hundreds of layoffs for the Novell workforce, including Mono developers,[11] putting the future of Mono in question.[12][13]

Founding of Xamarin

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. According to de Icaza, at least part of the original Mono team had moved to the new company.[14]

After this announcement, 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. 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.[15][16]

In July 2011, however, Novell - now a subsidiary of Attachmate - and Xamarin announced that Novell had granted a perpetual license for Mono, MonoTouch and Mono for Android to Xamarin, which formally and legally took official stewardship of the project.[17][18]

Product Development

In December 2012, Xamarin released Xamarin.Mac,[19] a plugin for the existing MonoDevelop Integrated development environment (IDE), which allows developers to build C#-based applications for the Apple OS X operating system and package them for publishing via the Apple App Store.

In February 2013, Xamarin announced the release of Xamarin 2.0.[20] The release included two main components: Xamarin Studio, a re-branding of its open-source IDE Monodevelop;[21] and integration with Visual Studio, Microsoft's IDE for the .NET Framework, allowing Visual Studio to be used for creating applications for Android and iOS, as well as for Windows.

Funding

On July 17, 2013 Xamarin announced that they had closed $16 million in Series B funding led by Lead Edge Capital.[22] Several investors from their Series A funding also participated, including Charles River Ventures, Floodgate, and Ignition Partners. On August 21, 2014 Xamarin successfully closed an additional $54 million in Series C funding, which is one of the largest rounds of funding ever raised by a mobile app development platform.[23] Total funding for the company to date is $82 million.[24]

Acquisition

On February 24, 2016 Xamarin and Microsoft announced that Microsoft signed a definitive agreement to acquire Xamarin.[7][25][26] Terms of the deal weren’t disclosed, though the WSJ reported the price at between $400 million and $500 million.

As a part of Microsoft

At Microsoft Build 2016 Microsoft announced that they'll open-source the Xamarin SDK and that they'll bundle it as a free tool within Microsoft Visual Studio's integrated development environment,[27] and Visual Studio Enterprise users would also get Xamarin's enterprise features free of charge. As a part of the acquisition they would also relicense Mono completely under the MIT License and would release all other Xamarin SDK software through the .NET Foundation also under the MIT License.[28][29]

Products

Xamarin Platform

Xamarin 2.0 was released in February 2013[30] Xamarin.Android and Xamarin.iOS that make it possible to do native Android, iOS and Windows development in C#, with either Visual Studio or Xamarin Studio. Developers re-use their existing C# code, and share significant code across device platforms. The product was used to make apps for several well-known companies including 3M, AT&T, HP, and Target.[31][32] Xamarin integrates with Visual Studio, Microsoft's IDE for the .NET Framework, extending Visual Studio for Android and iOS development.[21] Xamarin also released a component store to integrate backend systems, 3rd party libraries, cloud services and UI controls directly into mobile apps.[33][34]

Xamarin.Forms

Introduced in Xamarin 3 on May 28, 2014 and allows one to use portable controls subsets that are mapped to native controls of Android, iOS and Windows Phone.

Xamarin Test Cloud

Xamarin Test Cloud makes it possible to test mobile apps written in any language on real, non-jailbroken devices in the cloud. Xamarin Test Cloud uses object-based UI testing to simulate real user interactions.[35]

Xamarin for Visual Studio

Xamarin claims to be the only IDE that allows for native Android, iOS and Windows app development within Microsoft Visual Studio.[36] Xamarin supplies add-ins to Microsoft Visual Studio that allows developers to build Android, iOS, and Windows apps within the IDE using code completion and IntelliSense. Xamarin for Visual Studio also has extensions within Microsoft Visual Studio that provide support for the building, deploying, and debugging of apps on a simulator or a device.[37] In late 2013, Xamarin and Microsoft announced a partnership that included further technical integration and customer programs to make it possible for their joint developer bases to build for all mobile platforms.[38] In addition, Xamarin now includes support for Microsoft Portable Class Libraries[39] and most C# 5.0 features such as async/await. CEO and co-founder of Xamarin, Nat Friedman, announced the alliance at the launch of Visual Studio 2013 in New York.

On March 31, 2016 Microsoft announced that they were merging all of Xamarin's software with every version of Microsoft Visual Studio including Visual Studio Community (which shall receive Xamarin Studio Community), and this added various Xamarin features to come pre-installed in Visual Studio such as an iOS emulator.[40]

Xamarin Studio

Xamarin Studio, a standalone IDE for mobile app development,[21] was released in February 2013 as part of Xamarin 2.0 and is based on the open source project MonoDevelop.[41] In addition to a debugger, Xamarin Studio includes code completion in C#, an Android UI builder for creating user interfaces without XML, and integration with Xcode Interface Builder for iOS app design.[41][42] It is available on Windows and OS X.

Xamarin.Mac

Xamarin.Mac was created as a tool for Apple technology application development using the C# programming language. Xamarin.Mac, as with Xamarin.iOS and Xamarin.Android, gives developers up to 90% of code reuse across Android, iOS and Windows.[43] Xamarin.Mac gives C# developers the ability to build fully native Cocoa apps for Mac OS X and allows for native apps that can be put into the Mac App Store.[44][45]

.Net Mobility Scanner

Xamarin’s .Net Mobility Scanner lets developers see how much of their .NET code can run on other operating systems, specifically Android, iOS, Windows Phone, and Windows Store. It is a free Web-based service that uses Silverlight.[46]

RoboVM

In October 2015 Xamarin announced that they had acquired the Swedish RoboVM for Java developer platform akin to its offerings, the reason stated by Xamarin for the acquisition was that if they would develop a Java-based platform from the ground up that their end product would be similar to RoboVM so they acquired the company instead, as a result RoboVM operates independently of the Xamarin team. RoboVM enables developers to build Java apps for iOS and Android with fully native UIs, native performances, and all Java apps have the complete access to the APIs of each developer platform.[47][48]

In April 2016 Microsoft announced that they would discontinue RoboVM and cease all subscriptions after April 30th, 2017.[49]

Even if they aren’t supporting it, they do own a product that is in direct competition with Xamarin’s future offerings. Without some sort of legal arrangement between Attachmate and Xamarin, the latter would face the daunting prospect of proving that their new development doesn’t use any the technology that the old one did. Considering that this is really just a wrapper around the native API, it would be hard to prove you had a clean-room implementation even for a team that wasn’t intimately familiar with Attachmate’s code.
