I suppose most of you are pleased when some new cool add-in is released and it adds new feature to your favorite tool/utility. Most of us - developers - know about Reflector and it's ecosystem of useful add-ins.
Have you ever wanted to be able to create such applications without having to code by hand all these add-in infrastructure classes?!
Guess what?! New System.Addin namespace is coming with VS "Orcas" to facilitates you.
