Abstract

An arrangement is provided for selectively loading and executing an assembly based on platform capabilities. When an application that includes at least one platform capability-dependent assembly realized to perform a function is initiated on a platform of a device, the platform capabilities supported by the device are determined based on corresponding platform capability profiles. Based on the supported platform capabilities, specialized assemblies designed to perform an underlying function on a platform having the supported capabilities are selected. Proxies corresponding to selected specialized assemblies are then accordingly invoked to load and excuting the specialized assemblies.

7. The method according to claim 1, further comprising loading the specialized assembly prior to said executing.

8. The method according to claim 7, wherein said loading the specialized assembly comprises:

retrieving the specialized assembly from a local storage if the specialized assembly is locally stored; and

retrieving the specialized assembly from a remote location if the specialized assembly is not locally stored.

9. The method according to claim 8, wherein said retrieving from a remote location comprises:

determining the remote location where the specialized assembly is stored;

connecting to the remote location; and

downloading the specialized assembly from the remote location.

11. The system according to claim 9, wherein the platform comprises at least one capability profile, each of which describes a supported capability by the platform of the device.

12. The system according to claim 11, wherein the platform capability-dependent application includes:

at least one assembly, each of which has one or more specialized assemblies each of which requiring a different supported capability;

a platform capability-based assembly execution mechanism capable of selecting a specialized assembly requiring a specific platform capability based on the at least one supported capability of the platform determined according to the at least one capability profile; and

at least one proxy, each of which is associated with a corresponding specialized assembly, capable of accessing and executing the specialized assembly.

13. The system according to claim 12, wherein the specialized assembly is stored locally on the device and is retrieved by a corresponding proxy from a local storage.

14. The system according to claim 13, wherein the specialized assembly is stored remotely at a different location than the device and is downloaded by a corresponding proxy from the remote location.

15. The system according to claim 14, wherein the platform capability-based assembly execution mechanism comprises:

a required capability identification mechanism capable of identifying at least one required capability necessary for an assembly to be executed on the platform of the device;
