You'd still need the .NET framework installed, you cannot run .NET code without the framework.
But yes you can, you'd make the .NET code avaliable via COM and then reference it from within VBA. There are articles on creating managed plug-ins for Office in the MSDN library, this would be the best place to start.
There is also a .NET addin for developing managed code for Office. I think its called Office Tools for .NET, its quite expensive.
