Also can confirm. Even with just 2 developers the conflict resolution is extremely poor and most of the time it just "resolves" it automatically, the wrong way,

Also can confirm. Even with just 2 developers the conflict resolution is extremely poor and most of the time it just "resolves" it automatically, the wrong way, without telling you it even happened. VS integration has far less features than any third-party svn or git integration I've used. Getting it to ignore NuGet binaries is a pain. My current project is the first I've used TFVC on, it's only a few months old and there isn't really anything of value in the history. If the other guy agrees, I'm gonna move to git on the next slow day.
