where I was publishing replica of the MEF bits hopping that the Secured Directory Catalog will
find its way into the MEF core.
but as sad as it is , it won’t make into the core.
you can read more about the MEF team consideration here.
anyway Glenn Block has suggest a solution for haw to build the secured catalog
without rewriting half of the MEF core, so as you might guessed,
I had created new directory catalog that let you control the assembly loading of your plug-ins.
it is given without any warranty, but with full source code.
actually it is real small implementation which you should find easy to review.
so enjoy the secured way of the plug-ins injection.
