One of the more interesting aspects of moving to VisualStudio Online for my source control and builds when I did it was seeing that I now had the choice between TFS Version Control (TFSVC) and Git to use as my source control. At that time I had never used Git. However, when I saw this while Team Foundation Service was still in beta (before it became visualstudio.com) I told a buddy of mine. Who worked for Microsoft. And from what he knows, it sounds like MS is on its way to deprecating TFSVC in favor of Git, hence the dual offering.
With this in mind, let’s see how we can also deprecate our source control repos in favor of Git, AND migrate them to visualstudio.com!
