Abstract

A virtual application may be configured with several extension points within a host operating system. The virtual application may be configured with a private namespace in which various components, such as registry settings, dynamic linked libraries, and other components may reside. During configuration, links may be placed in the host operating system that may point to objects in the virtual application'"'"'s private namespace so that the operating system and other applications may launch, control, or otherwise interact with the virtual application. The links may be located in a file system, registry, or other locations and may be available to other applications, including other virtual applications. A configuration routine may place the links into the host operating system at the time the application may be configured.

Claims

1. A system, the system comprising:

a processor;

system memory coupled the processor, the system memory storing instructions that are executable by the processor; and

the processor executing the instructions stored in the system memory to operate a virtual application at the computer system, including the following;

formulate a link into a private namespace, the link providing an extension point for accessing a stored item related to the virtual application, the private namespace private to the virtual application to prevent another application at the computer system from natively accessing the stored item, the link permitting the other application to interact with the virtual application in a specified manner by accessing the stored item;

store the link in a public namespace at the system to make the link selectable by the other application; and

in response to receiving a selection of the link in the public namespace by the other application, identify the stored item from the link and permit the other application to interact with the virtual application in the specified manner through access to the stored item.

2. The system of claim 1, further comprising the processor executing the instructions stored in the system memory to:

formulate a second link into the private namespace to provide an extension point for accessing a second stored item related to the virtual application, the second stored item stored in the private namespace; and

store the second link in the public namespace.

3. The system of claim 2, wherein the processor executing the instructions stored in the system memory to formulate a second link into the private namespace comprises the processor executing the instructions stored in the system memory to formulate a second link in one of:

a host file system of the system or a host registry of the system.

4. The system of claim 1, further comprising the processor executing the instructions stored in the system memory to install an application virutalizer for the virtual application, the application virtualizer configured to receive a selection of the link from an application and permit the application to interact with the virtual application in the specified manner through access to the stored item.

5. The system of claim 1, further comprising the processor executing the instructions stored in the system memory to:

process a manifest including the link; and

identify the link from within the manifest.

6. The system of claim 1, further comprising the processor executing the instructions stored in the system memory to install a streaming client, the streaming client for communicating with a streaming server to fetch portions of the virtual application.

7. The system of claim 1, wherein the processor executing the instructions stored in the system memory to formulate a link into a private namespace comprises the processor executing the instructions stored in the system memory to formulate a link that permits one of:

passing parameters to the virtual application and traversing configuration information for the virtual application.

8. The system of claim 1, the processor executing the instructions stored in the system memory to formulate a link into a private namespace comprises the processor executing the instructions stored in the system memory to formulate a link from one of:

a file system in said public namespace or a registry in said public namespace, into said private namespace.

9. The system of claim 1, further comprising the processor executing the instructions stored in the system memory to create the private namespace.

10. The system of claim 1, further comprising the processor executing the instructions stored in the system memory to install the virtual application in the private namespace.

11. The system of claim 1, wherein the processor executing the instructions stored in the system memory to store the link in a public namespace at the system to make the link selectable by the other application comprises the store the link in a public namespace of a host operating system to make the link accessible by the other application;

and

further comprising the processor executing the instructions stored in the system memory to;

receive a selection of the link through the public namespace by the application from among the one or more other applications; and

in response to receiving selection of the link in the public namespace by the other application, identify the stored item from the link.

12. A system, the system comprising:

a processor;

system memory coupled the processor, the system memory storing instructions that are executable by the processor; and

the processor executing the instructions stored in the system memory to access a virtual application, including the following;

receive an indication that a link to a virtual application has been stored in a public namespace to make the link accessible to another application, the link providing an extension point for accessing a stored item related to the virtual application, the private namespace private to the virtual application to prevent the other application from natively accessing the stored item, the link permitting the other application to interact with the virtual application in a specified manner by accessing the stored item;

monitor the link to detect a selection of the link by the other application through the public namespace; and

in response to monitoring selection of the link in the public namespace by the other application, permit the other application to interact with the virtual application in the specified manner through access to the stored item, including identifying the stored item from the link.

13. The system of claim 12, wherein the processor executing the instructions stored in the system memory to receive an indication that a link to a virtual application has been stored in a public namespace comprises the processor executing the instructions stored in the system memory to receive an indication that the link has been stored in a file system at the system.

14. The system of claim 12, wherein the processor executing the instructions stored in the system memory to receive an indication that a link to a virtual application has been stored in a public namespace comprises the processor executing the instructions stored in the system memory to receive an indication that the link has been stored in a registry at the system.

15. The system of claim 12, wherein the processor executing the instructions stored in the system memory to interact with the virtual application in the specified manner comprises the processor executing the instructions stored in the system memory to launch to the virtual application.

16. The system of claim 12, wherein the processor executing the instructions stored in the system memory to interact with the virtual application in the specified manner comprises the processor executing the instructions stored in the system memory to pass parameters to the virtual application.

17. The system of claim 12, wherein the processor executing the instructions stored in the system memory to interact with the virtual application in the specified manner comprises the processor executing the instructions stored in the system memory to examine configuration information for the virtual application.

18. The system of claim 12, wherein the processor executing the instructions stored in the system memory to interact with the virtual application in the specified manner comprises the processor executing the instructions stored in the system memory to receive a value for a registry key, the registry key value in a registry in the private namespace.

19. The system of claim 12, further comprising the processor executing the instructions stored in the system memory to use a streaming client to receive part of the virtual application through streaming.

20. The system of claim 12, wherein the link is configured so that the other application can interact with the virtual application in the specified manner by accessing the stored item.
