The initial download and subsequent upgrades do not require special installation procedures or update procedures.

The initial download does not need to contain all components of the application. Thus, the end user's machine is not cluttered with application components that are never used.

When the application deployer updates the application, WebClient on the end user's machine automatically downloads only the application-component elements that have changed, making downloads faster.

Application components (for the initial download and for updates) can be hosted on an AppServer as well as on a Web server.
