Reviews for this release

I have been following MEF for a while now, another example of an invasive clunky framework, too much time was spent arguing about the concept as opposed to implementing it properly. So many contributors and documentation is not even complete. Pathetic...

While the concept of this project is really, very cool I have to say the overall project itself is very, very poor! Or, if you prefer, typical of how Microsoft operates. This project has NO updated samples, no documentation (new) just a reference in a read me that says the IDE project is the latest. At least have the professionalism to remove all the old stuff. DON"T WASTE YOUR TIME

really nice improvements to the typing, inheritance behavior and a controllable/sane recomposition strategy
