SlimDX is a free open source framework that enables developers to easily build DirectX applications using .NET technologies such as C#, VB.NET, and IronPython. It is designed to be an efficient, simple, and lean wrapper that fully encompasses all of Microsoft's gaming and multimedia technologies and exposes them to managed code. All of the code is under the MIT/X11 license, and all content is under the Creative Commons Attribution-Share Alike license.
Please note that while SlimDX is similar to Managed DirectX, it is NOT intended to be the same API. More information, as well as documentation and other support, can be found at our homepage at http://slimdx.org.
This GitHub repository hosts V2 of SlimDX, which is a work in progress. You can find the stable main branch at our old Google Code site.
