Is there a multi-directory DirectoryCatalog available in MEF or open source?

I'd like to separate extensions into their own subdirectory of some Extensions directory. I can specify multiple DirectoryCatalog of course and put them into an AggregateCatalog. But I have开发者_开发百科 to go scan that directory and create those. Not a big deal, but is there something like MultiDirectoryCatalog out there?

Nope the best you will be able to do is an AggregateCatalog with a multiple DirectoryCatalogs. At least with what ships in the .NET Framework itself.
