Check out Data Dude!
If somehow you've missed all the excitement about Visual Studio Team Edition for DB Pros (aka Data Dude), I'd highly recommend that you check out their latest Community Tech Preview. Read Cameron's blog to learn all the nitty gritty details, but by all means, if you're interested in database development in a team environment (who isn't?), you've got to check this release out. They're very, very close to closing things down so this is one of your last chances to try it out before it goes golden.
