Visual Studio Team Foundation Server 2015 provides the collaboration hub at the center of the Microsoft Application Lifecycle Management (ALM) solution. By automating the software delivery process, entire teams can track team actions, transactions, and project artifacts such as requirements, tasks, bugs, source code, build results, and test results. Collaborate, manage your repositories and automate build processes. Your team might be small and just getting started, but with Team Foundation Server, even the smallest team can go big.

Note: TFS Express is limited to five (5) users. Larger teams can use Visual Studio Team Foundation Server 2015.
