If you’ve been following the conversation between Jacob Proffitt and myself about dependency injection, Ayende Rahien has added his thoughts to the topic as well in two posts on his own blog:

Dependency Injection: More than a testing seam
Dependency Injection: IAmDonQuixote?

This started from Jacob’s first post on his blog, which I commented on, and it spun off into an article on my own blog (and continued in the comments). It’s turned into a very interesting conversation on the merits of dependency injection versus alternatives such as the provider model used in ADO.NET.

Update: Aaron from Eleutian has also joined the conversation.
Update 2: Eli Lopian (of TypeMock fame) has also presented his stance.
