A system and method for an extendable application framework, comprising a user interface, at least one service, at least one extension, wherein one of the at least one extensions can provide access to functionality in the user interface, and wherein one of the at least one services can provide access to functionality in one of the at least one extensions.

System and method for describing application extensions in XML

An application service provision apparatus is provided with one or more components to perform a dispatching and a shared resource monitoring function to allow applications be hosted with multiple versions of a hosting service runtime library in a more efficient manner. The dispatching function, upon receipt of a request for service for an application, determines if the version of the runtime library required is known. If not, the dispatching function turns to the latest version of the runtime library to determine the version required. In one embodiment, the required earlier versions are loaded only on an as needed basis. The shared resource monitoring function, upon detecting aggregated allocation of a shared resource reaching a pre-determined threshold, requests consumers of the shared resource to provide tracked last used times of their allocations. In response, the monitoring function selects a number of the allocations for release, and instructed the shared resource consumers accordingly.

Multi-version hosting of application services

Successor versions of an application service provision runtime library of an application service provision apparatus are provided with corresponding update services to facilitate upgrade of applications to selected ones of the successor versions on request. In various embodiments, a dispatcher of the application service provision apparatus is provided with complementary functions to coordinate the servicing of the upgrade requests. In some embodiments, each of the update services is equipped to upgrade the application from an immediate predecessor version of the runtime library. In other embodiments, each of the update services is equipped to upgrade the application from any predecessor version of the runtime library.
