Abstract
The operating system organizes software so the set of extensions for an extendable application can be dynamically discovered and the extension can be run securely. Extensions are run as separate applications instead of within the extendable application's process. Extensions are discoverable to an activated extendable application by querying a category catalog. A category provides at least a partial description of a contract between an activating software entity and a software entity that is activated by the activating software entity. The category may enumerate a set of configuration settings associated with the contract that may be used to set up an isolated execution environment for the activated software entity. The category may also specify one or more extension points to be used for communication between the activating and activated software entities. The category may also include a list of software entities that implement the category.
