To change TFS server connection settings, use the Set Up button on the Application Development tab:
The settings need to be changed if different branches are created on the server for different project versions. The names and the number of files in each branch must be identical.
Clicking the Synchronize Repository button allows to get and save the latest version of the object from the server into the repository. This command must be executed before disconnection of repository from the version control system.
