The live service can be found at Team Foundation Service. There are downloads so that it can hook into Eclipse and a command-line to use with xcode. This provides developers of many different types of apps from iOS, to Android, to WP7/8, or any Windows apps. VS2010 or VS2012 are needed to connect to this service. Some good news is that the site also shows that the free VS2012 Express tools can also use the service. I think this might be the first time that the Express SKUs could access TFS. One concern I had was what were they going to have as a free subscription level and how much was the paid version. So for free, Microsoft is offering:
If you need more than 5 users then in 2013 the paid plans will be announced. But for us little guys, this is a great free service. It definitely beats some of the other TFS hosting services by making this free.
