A large number of the UK’s Universities and colleges have been using XNA since 2004 within gaming course curricula on Windows, XBox and Windows Phone. We have a huge set of Free curricula resources for XNA game development at http://www.microsoft.com/faculty
XNA over the last 7 years has provide a number of students and indie game developers with an impressive content pipeline, game assets, load functionality, animation, math, sound and user input tracking via gamepad, mouse, keyboard and touch with game logic organized in a straightforward game loop architecture, more recently we have also added curricula for XNA and Kinect.
Within education XNA has been a huge driver for a number of students and developers who wanted to learn how to create games. XNA along with Visual Studio made it as easy as File –> New –> XNA Game Studio Project and you were off developing.
Since Windows 8 is built on the strong foundation of Windows 7, any app built for Windows will run in the Windows 8 desktop environment. This includes apps based on XNA, Win32, .NET, WPF, Silverlight, etc.
Windows 8 also introduces a new type of app called a Metro Style App for developers that wish to make their app available in the Windows 8 Store, for free or for sale. Using Visual Studio 2012, you have a language choice of C++, XAML with C#, VB or C++, or HTML5/JS to create a Metro Style App.
Using the XNA Framework is not a choice for building a Metro Style App. Official Microsoft guidance on game development is documented here.
Windows 8 allows you too build highly immersive games using HTML5/JS, XAML/C#, XAML/VB or C++ and DirectX.
However a number of you have already stressed too me, that you and your students have been developing with XNA and have an existing code base, or would like to import existing XNA games too Windows 8 your only option it would seem is running as a desktop app.
This is where MonoGame comes in…
MonoGame is an Open Source implementation of the Microsoft XNA 4 Framework. The goal is to allow XNA developers on Windows & Windows Phone to port their games to the iOS, Android, Mac OS X, Linux with both PlayStation Suite and Windows 8 support currently under development.
MonoGame provides a cross platform XNA Framework implementation for XNA developers who want to take their code to non-Microsoft platforms as well as the ability, to target Windows 8.
MonoGame for Windows 8 you can take your XNA code and with a recompile and some additional features too simply create a Metro Style App for example Armed within the Windows Store uses MonoGame. I have too stress MonoGame is still under development and so any use of it should come with a note of advice to stay on top of that effort.
In order to provide a complete implementation of XNA on Windows 8, MonoGame leverages SharpDX , an open-source project delivering the full DirectX API for managed code (.NET) and Windows 8 (WinRT). SharpDX is an open-source project, free of charge available under the following MIT License.
Theoretically by moving your code over into a new Visual Studio Project Solution along with MonoGame, you should de able too recompile a Windows 8 Metro Style game so if your a XNA Developer give it a try and let me know the results.
