Given a changeset number say C12345, how does one get a list of all changesets that have followed after C12345 that may or may not have been pulled down from the TFS server?
From the root, call:
tf history . /r /noprompt /V:C#####~T
Note: C12345 will be included at the tail of the list.
So in your case it would be:
tf history . /r /noprompt /V:C12345~T
