Version Control in Visual Studio
Version control systems help you track changes to code over time. As you make changes, the version control system takes a snapshot of your files. The version control system saves that snapshot permanently so you can recall it later if you need it. Visual Studio provides Git and Team Foundation Version Control (TFVC). To decide between the two systems, see Choosing the right version control for your project.
Git is the most commonly used version control system today and is quickly becoming the standard for version control. Git is a distributed version control system, meaning your local copy of code is a complete version control repository. These fully functional local repositories make it is easy to work offline or remotely. You commit your work locally, and then sync your copy of the repository with the copy on the server. This paradigm differs from centralized version control where clients must synchronize code with a server before creating new versions of code.
Team Foundation Version Control (TFVC) is a centralized version control system. Typically, team members have only one version of each file on their dev machines. Historical data is maintained only on the server. Branches are path-based and created on the server.
