One or more extension registrations are received for each of multiple software components installed on a computing device. The one or more extension registrations identify the software components as providers of functionality. A record of the one or more extension registrations for each of the multiple software components is maintained. Requests are received, from other software components installed on the computing device, that identify particular functionality. In response to such requests, the information regarding one or more of the multiple software components that provide the particular functionality is returned to the other software components.

Managed system extensibility

Multiple software component identifiers are maintained in a catalog of an operating system running on a device. Each of these software component identifiers corresponds to one of multiple software components installed on the device. The catalog is accessed in response to a request regarding one of the multiple software components, and the request is responded to based at least in part on information included in the catalog. Additionally, two or more versions of a software component that are installed on the computing device can be identified. Which one of the two or more versions of the software component is an active version of the software component to be run is determined. In response to requests for information regarding the software component, information regarding the active version of the software component is returned.

Catalog-based software component management

A method and system for dynamically downloading custom code for execution within a host application is provided. A deployment system augments the manifest used for deploying managed applications to include information describing how the host application is to use the custom code, referred to as host manifest information. The deployment system reports the progress of the downloading of the manifest and the custom code to the host application. The host application can then perform appropriate host-specific processing. The host application may provide to the deployment system an interface for verifying the trust of the custom code. The deployment system also allows the host application to control the uninstalling of the custom code.

Dynamic deployment of custom code

Described is a mechanism for enabling an application operating as a web application to transition to a client-side application without impacting a user's interaction with the application. The progressive installation transitions through three states: a start-up state, a demand state, and an install state. During the start-up state, a subset of components associated with the application is downloaded and stored in a local data store. The subset is sufficient to allow execution of the application in a manner similar to a web application. During the demand state, additional resources associated with the application are downloaded. Transitioning from the demand state to the installed state occurs without impacting a user's interaction with the application. The transition may occur autonomously based on the number of additional resources stored in the local data store or upon an external trigger.

System and method for progressively installing a software application

A method and system for increasing perceived Internet browser performance by using a relatively high-bandwidth data source such as a CD-ROM and/or a hard drive directory as a local cache of Internet content. The content is provided by content providers via some high-bandwidth data source such as a CD-ROM media for a CD-ROM drive. An install program provided with the content registers with the system one or more URL patterns such as prefixes corresponding to the content, in association with one or more file system patterns (e.g., prefixes) corresponding to a cache container (file system directory). When subsequently browsing to a URL having a matching pattern, the URL pattern is resolved to the cache container, which is then used with the rest of the URL to construct a local file reference. The local file is accessed from the high-bandwidth data source. If the local file is not found, the original http URL is instead used, whereby the content is downloaded in the normal manner. The installable cache may reside on a CD-ROM or other removable media, whereby an autorun program or script that executes each time the media is inserted into a drive updates the registered drive letter.
