We are about to setup a cruise control.net with and NAnt and TFS, do I need visual studio 2005/2008 with team explorer installed or can I make this work with just the free T
Team Explorer will install the VS shell, which gives it enough of VS to operate.
So strictly the answer is "yes, Team Explorer requires VS", but since VS is included in the Team Explorer install the strict answer is kind of unhelpful :-).
Once Team Explorer is installed, you get access to the TF.EXE command line tool, but also worth looking at the TFS Power Toys for the tftp.exe command line tool and the PowerShell Snapin for more command line operation.
