I was wondering if someone can tell me if there is any changes in how events are sent and received in tfs 2012. I searched the website and it looks like it's pretty much the same except another UI is added in 2012. Is there any other interior changes? Thanks for the help!
Mostly the same, new UI, that's the right description. Even on the server side things have remained mostly the same, but some types have moved from one assembly to the other, so there are some implementation changes that are otherwise invisible to a normal user.
