Visual Studio → Extensions… → Gallery → Version Control → Team Foundation Control for TFS and VSTS → Install….
Prior to get the latest version you must install the extension, connect to VSTS and create a workspace: It is very convenient to have version control embedded into IDE and don’t need to launch separate app which isn’t indeed very productive. TFVS in Visual Studio for Mac is still in preview but it already can replace Team Explorer Everywhere for Eclipse or TFS extension for Visual Studio Code. Visual Studio Team Services are also price friendly because GitHub wants developers charge for private repositories. Visual Studio supports Git since 2014 so absolute majority of projects are controlled under TFVC. It illogically supported Git instead of TFVC.
Microsoft announced the release of Visual Studio for Mac one year ago.
