Abstract

Application compatibility is facilitated by use of library operating systems. Library operating systems can encapsulate portions of an application likely to break application compatibility. An application can be bound to a compatible library operating system that operates over a host operating system. Furthermore, library operating system version can be greater than, equal, or less than the version of the host operating system. Consequently, both backward and forward compatibility is enabled.

First claim

What is claimed is:

1. A method that facilitates compatibility, comprising:
employing at least one processor configured to execute computer-executable instructions stored in memory to perform the following acts:
identifying, at a runtime of an application, a library operating system that is compatible with the application, wherein the identified library operating system consists of application services executable in an isolation container, and the identified library operating system is configured to communicate with operating-system hardware services and user services of a host operating system;
locating the identified library operating system; and
in response to the identifying of the library operating system, binding the application to the identified library operating system.

2. The method of claim 1 , wherein the identifying of the library operating system includes:
identifying the library operating system from a manifest file.

3. The method of claim 1 , wherein the identifying of the library operating system includes:
identifying multiple library operating systems from a manifest file.

4. The method of claim 1 , wherein the library operating system is of a more recent version than the host operating system.

5. The method of claim 1 , wherein the acts further comprise:
loading the identified library operating system from the host operating system.

6. The method of claim 1 , wherein the acts further comprise:
acquiring the identified library operating system as part of an update process for the host operating system.

7. The method of claim 1 , wherein the acts further comprise:
updating the identified library operating system as part of an update process for the host operating system.

8. The method of claim 1 , wherein the acts further comprise:
replacing a first version of the host operating system with a second version of the host operating system; and
binding the application to the library operating system corresponding to the first version of the host operating system.

9. The method of claim 1 , wherein the locating of the identified library operating system includes:
locating a most recent version of the identified library operating system.

10. A computing device, comprising:
a memory and a processor, wherein the memory and the processor are respectively configured to store and execute instructions, including instructions for causing the computer to perform the following operations:
identifying, at a runtime of an application, a library operating system that is compatible with the application, wherein the identified library operating system consists of application services executable in an isolation container, and wherein the identified library operating system is configured to communicate with operating-system hardware services and user services of a host operating system; and
in response to the identifying of the library operating system, binding the application to the identified library operating system.

11. The computing device of claim 10 , wherein the identified library operating system is packaged with the host operating system.

12. The computing device of claim 10 , wherein the identified library operating system is a more recent version of the host operating system.

13. The computing device of claim 10 , wherein the identified library operating system is an older version of the host operating system.

14. The computing device of claim 10 , wherein the operations also include:
locating the identified library operating system based on information from a manifest file.

15. The computing device of claim 10 , wherein the operations also include:
updating the identified library operating system as part of an update process for the host operating system.

16. The computing device of claim 10 , wherein the operations also include:
acquiring the identified library operating system as part of an update process for the host operating system.

17. A computer-readable storage medium, having instructions stored thereon, that in response to execution, cause a computing device to perform operations, the operations comprising:
identifying, at a runtime of an application, a library operating system that is compatible with the application, wherein the identified library operating system consists of application services executable in an isolation container, and the identified library operating system is configured to communicate with operating-system hardware services and user services of a host operating system;
locating the identified library operating system; and
in response to the identifying of the library operating system, binding the application with the identified library operating system.

18. The computer-readable storage medium of claim 17 , wherein the operations further comprise:
identifying the identified library operating system based on information from a manifest file.

19. The computer-readable storage medium of claim 17 , wherein the operations further comprise:
identifying a new version of the host operating system as the identified library operating system.

20. The computer-readable storage medium of claim 17 , wherein the operations further comprise:
identifying a legacy version of the host operating system as the identified library operating system.
