In case you haven’t heard yet, we have announced the RTM of our Team Foundation Service. Our long-term vision is to have up to 5 users free at all times and then some pricing model for over 5 users. Currently it is all free to my knowledge. Here is a blurb from the main site:
Plan projects, collaborate with your team, and manage your code online from anywhere.
Check your code directly into the cloud using Visual Studio or Eclipse. Manage work items and bugs in Internet Explorer, Chrome, or Safari.
