XNative is a set of managed wrapper libraries to make native DirectX 11 APIs accesible on managed code projects.
Taking DirectX API Library, from Microsoft's API Code Pack 1.1, as starting point, we have a lot of useful code to convert it to DirectX 11.1 managed library.
That conversión must delete all references to DirectX10 and DirectX10.1, so DirectX11.1 handles lower caps graphics devices, without need to implement older versions.
For now, we only get these files, and made empty projects for further development. If you want to participate, feel free to contact project's members.
