The developer can specify the update behavior; a network administrator can also control update strategies, for example, marking an update as mandatory. Updates can also be rolled back to an earlier version by the end user or by an administrator. "

Your app can automatically check for updates on startup and download any updated assemblies in the background so that they are available on the next startup. If any bugs are inadvertently present in the update then the rollback option is a godsend ! :-}
