Whilst writing some training material for VSTS I hit a problem creating a TFVC workspace. I was using VS2017, linking a TFVC Repo to a local folder. I was connecting to the VSTS instance using an MSA.
In Team Explorer, when I came to do a ‘Map & Get’ to map the source locations I got a ‘TF14061: The workspace ws_1_18;Project Collection Build Service does not exist’ error
Strange error, which I could see no obvious reason for. Turns out the work around was just to press the ‘Advanced’ link/button and accept the defaults
