How long i’ve been looking for some concrete list of interfaces – god knows. There is only this category-like list of possible extensible areas. but that’s not good enough.

went to Reflector, and analyzed all the usages of ImportAttribute in the visual studio assemblies.

For future lookup, here’s the full list of interfaces that can (and are) used to extend visual studio 2010 functionality. I’m sure most of it is not usable , but it’s good to know just how big this ecosystem is.

nice and simple, eh? (1.1 mb file of this image is here)
