An interface mechanism is provided for developers to bundle together a set of extensions (or add-ins) to a productivity suite allowing end users and system administrators to manage their lifecycle in a unified way. Aspects such as discovery, acquisition, authorization deployment, management, updates, and similar ones may be addressed for the bundle as opposed to each of the different extensions (for example extensions for different versions of the same application such as desktop version, web application version, mobile version, etc.). Bundles may also provide a means to match specific functional sets or commercial offerings to specific user or customer profiles.
