Castle Windsor: So what DOES ActAs do?

Question

I noticed that the castle windsor fluent component registration interface has the rather confusing ActAs() method.

Googling around for it the only reference I found was at their wiki here.

TODO (Stuff that could be documented)

• what does ActAs() do?

Not too helpful.

The source doesn't seem to have any unit tests for the method that would give a clue to its usage and I'm too unfamiliar with their source to be able to tell for myself what is going on.

Does anyone know any more about this?

Answer 1

It adds custom dependencies (tags) to the component being registered. The WcfFacility, for example, uses these attached dependencies to set up endpoints and other stuff.
