Some time ago I blogged about a tool to manage users and groups across WSS, Reporting Services and Team Foundation.
This has been available in Beta in the past, but only running against old builds. The Developer Division Aftermarket Solutions team has just updated the binaries to run against the Release Candidate of Team Foundation.
They blogged about the update here - other links for the tool are:
Note - this should work against the final bits we release at RTM - I'm 99.99999% certain we won't take any last minute bug fixes that would break compatibility between RC and RTM.
What other Team Foundation tools would you like?
