Msdn Command
Displays a help topic from the MSDN library that contains detailed information about a Team Foundation version control command.
tf msdn commandname
When you need a command and are not sure which one to use, type tf msdn for a list of command reference topics and links to additional resources. If you use the msdn command without specifying a commandname parameter, you will see a topic that lists all commands together with usage requirements and a description.
When you specify the commandname parameter, the help topic opens for that specific command. If the system cannot find a match for the commandname, it searches for aliases and short names. If it does not find a matching command, alias, or short name, you will get an error message.
