I have posted the slides and demos for two of my three NECC14 talks that I did yesterday (Oct 2nd) on the downloads page of my book’s website at http://learnentityframework.com/downloads/#conf
You’ll find the demos for Persistence Ignorant Entity Framework 4 and n-Tier ASP.NET Web Forms Apps with Entity Framework. Look in the conference section.
The slides are on SlideShare (www.slideshare.net/julielerman).
I did a third talk (Unit Testing for ‘Fraidy Cats Like Me” but it did not have a powerpoint and is not a talk that generated demos.
