During installation, the registration data must be included in the Team Foundation Server registration database. Do this by using the TFSReg command-line utility to use an XML file and the registration configuration file that represents the registration data.
The registration entries can be either added separately or all together. TFSReg supports delete, update and export operations. Default behavior is updating the registration entries. The /D option is used to delete the entries in the configuration file. The /Export option is used to export the current registration configuration file into a file that you specify.
You can also use the registration configuration file to configure an extension to Team Foundation Server, for example, you could add information to increase the capabilities of the Team Project Requirements Manager.
