I like having my editor and my build environment integrated with my source control, even if that source control is Source Safe (ugh.) I like being able to check in and out from Solution Explorer rather than a separate tool, and settings like “check out on edit” are handy too. But you know what I really want to be able to do? Right click a line of code and ask “who wrote this?” The answer would be the date, user id, and check-in comment from the last time a touch of that file affected that line of code. Anyone who has ever managed a team project has looked at a block of code, done a double-take, and then demanded of the air “who the %^^$# put that in there?” I want my editing environment to tell me that.
The information to do this is in the system. I can do it by hand by doing a Diff between versions until I find two versions where that line changed, then looking at the check-in details. But it's just the kind of boring job that's perfect for a computer.
I wonder if the source control in VSTS does this?
