Described is a technology in which one application running in a browser can host another application (e.g., an advertisement) in an isolated manner that prevents the hosted application from accessing browser data, or data of any other hosted application (including the host). The host and/or hosted application may be a browser plug-in (e.g., Microsoft&#xae; Silverlight&#x2122;) application. The host application privately instantiates a hidden plug-in, with that hidden plug-in's access to browser data disabled, and loads the hosted application in the hidden plug-in. A XAML tag element may be used to identify the hosted application, along with a rendering area for the hosted application. Content from the hosted application is composited with content from the host application when rendering. The host application may provide keywords to the hosted application, such as for selecting relevant advertisements, and/or may allow the hosted application to open a browser window to display associated website content.

Isolating applications hosted by plug-in code

Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.

Media streams from containers processed by hosted code

A media interaction system is described herein that allows hosted applications to consume and/or produce rich media content independent of the format of the media content, while still maintaining the security of the host. The media interaction system accepts raw, uncompressed media data from a hosted application, and allows the hosted application to provide its own codec through a sandboxed API that restricts the actions the codec can perform to a set of trusted actions. Then, the application provides the uncompressed data to the system for playback. Thus, the media interaction system provides rich media content in any format that the application developer supports, and maintains the security of the user's computer system.

Hosted application platform with extensible media format

Extensions or additional software programs that are requested by a computer application running on an application platform are handled in an efficient manner by, among other things, regulating and tracking extensions that are downloaded. This allows the size of the application platform upon which the application is running to remain relatively small so as to mitigate strain on resources when the platform is initially deployed over a network (e.g., the Internet), thus making it easier and more likely for a user to install the application platform (and/or updates thereto). Requested extensions are subsequently added to and/or removed from the (already deployed) application platform based on, among other things, download metrics.

Application loading

In a computing environment, one may wish to have interoperability between trusted and untrusted controls/plug-ins allowing for richer expression of content and control within a platform. This can be accomplished by allowing an untrusted plug-in to communicate with a trusted plug-in, while having the trusted plug-in exercise control over the platform. This allows for the creation of a layered secure approach of communication with a platform, thus allowing for increased application richness in untrusted third party applications.

Untrusted component hosting

The present invention relates to systems and methods that provide automatic generation of user interfaces via creation of a class-based model. A system is provided that facilitates generating a user interface. The system includes a class component to generally define properties and methods associated with one or more interface actions. A service component parses the class to automatically generate all or a portion of a user interface from the interface actions. Push and Pull-type models can be provided to facilitate merging of actions from various classes such as provided by third parties or from existing component developments.

Explicitly defining user interface through class definition

A user interface is provided that exposes items such as developer tasks, commands, property settings, and other related information to a user. The user interface may be invoked in a number of development interfaces such as, for example, a designer or an editor. The user interface may be either an object bound interface or an action triggered interface. An object bound interface exposes a set of items that are associated with a corresponding object. An action triggered interface exposes a set of items that are associated with a corresponding triggering action. In addition to enumerating developer tasks, the user interface may provide a direct link to other interfaces that facilitate task execution.
