Not showing up on the first page if you search around, but I think it currently is the best article around that shows the new stuff:

Wow, I was really surprised when starting my session. Had the last presentation slot at the last day so didn't expect a whole lot of people. But it turned out to be pretty different, there actually wasn't enough space for everybody, people had to stand in the back.
Find the slide deck of my presentation below if you want to re read some stuff.
Also I blogged about some of these practices with some more detail as in the slidedecks. You can find them here: http://bloggingabout.net/blogs/gerben/archive/2010/02/01/wcf-best-practices.aspx.
Just let me know if you have any additional questions!
