SVN: It is possible to perform ‘in-place’ editing of artifacts. To reflect changes back to the repository, we have to commit the changes.
TFS: It is not possible to perform ‘in-place’ editing of artifacts in the ‘mapped’ directory. To perform in-place editing, we need to explicitly ‘check-out and lock’ the artifact for editing. Till such time, the artifact in the mapped directory is in ‘read-only’ mode.
