Slides from the Design Patterns & Testability session at dotNED 

As usual, I ran out of time big time, but still, it was a great evening. We continued until 21:45 and even though my throat was hurting as hell due to the flu, people were paying attention very well. TDD en testability are really difficult subjects and always cause a lot of discussion, but the discussion itself already proved some of the claims I made. So, I'm happy!

You can download the slides here and the code that shows all the examples I had in mind (and failed to show within the available time) here.
