Microsoft XNA Game Studio

Microsoft XNA Game Studio is a discontinued integrated development environment (IDE) for building video games on the Microsoft XNA platform. Such video games can run on Xbox 360, Microsoft Windows, Windows Phone and the Zune. XNA Game Studio is targeted at hobbyists and experienced programmers, and is primarily used to develop 2D and 3D video games for various Microsoft platforms. XNA games can be published for the Xbox 360 using an XNA Creator's Club membership, that has a yearly fee.

Five versions have been released so far, and in 2013, Microsoft stated that it would cease support for XNA in April 2014, and there are no plans to release any further versions. An open-source spiritual successor / API re-implementation exists in the form of the MonoGame framework.

XNA Game Studio Express
XNA Game Studio Express, the first release of XNA Game Studio, was intended for students, hobbyists, and independent (and homebrew) game developers. It was available as a free download. Express provides basic "starter kits" for rapid development of specific genres of games, such as platform games, real-time strategy, and first-person shooters. Developers could create Windows games for free with the XNA Framework, but to run their games on the Xbox 360 they will have to pay an annual fee of US$99 (or a four-month fee of US$49) for admission to the Microsoft XNA Creator's Club. The initial release had no way of shipping precompiled binaries to other Xbox 360 players, but this was changed in "XNA Game Studio Express 1.0 Refresh" which made it possible to compile Xbox 360 binaries and share them with other Microsoft XNA Creator's Club members.

The first beta version of XNA Game Studio Express was released for download on August 28, 2006 followed by a second version on November 1, 2006. Microsoft released the final version on December 11, 2006.

On April 24, 2007, Microsoft released an update called XNA Game Studio Express 1.0 Refresh.
