I hope NDC Conferences could upload 1080p or higher. Codes are hard to read in situations like 40:03. Great talk and indeed, something wrong with the sound.
Please...just...don't If you want to get real real world, look into impedance mismatch and practical solutions. Automapper? Seriously? Just write your own mapping logic, it's much easier to maintain and understand. And one less dependency you have to maintain. ORM's are not your friend, and by the time you need solutions like this, you are just trying to break out the box that EF put you in in the first place. All the best to the author, and it is interesting to know how EF and AutoMapper work, but I would be very careful implementing overly complex solutions like those offered here in the real world.
