Glad to see everyone last night at this presentation, it was quite enjoyable, great questions from the audience as well which always makes my day! Here's the link to the site with access to my slide deck and other resources:

You can get the Enterprise Services sample from there, and a reference to my article which provide more detail. In addition, I demonstrated some asynchronous handler examples, but I found a great article from Fritz Onion on the subject, so here's the link to his article with access to his samples for the article, that will be even more detailed from that I demonstrated:

If you are new to handlers, check out my handlers page, with reference to some other articles I've written as well:
