Abstract: A computing device includes a deployment engine to communicate with a deployment repository that includes metadata that is used in the deployment of an application. The metadata may include references or links to resources to be included in the deployment of the application. The deployment engine determines whether the deployment repository contains new or updated metadata and/or resources that the computing device can download. The metadata includes information that allows the deployment engine to correctly deploy or update an application on the computing device.

Abstract: Metadata is used to create customized user interface (UI) portions for an application. The metadata may be XML-based and can be interpreted and then rendered to implement a customized UI that also supports data binding between data and the UI controls. Once created, the metadata is processed by a rendering engine to display the UI controls. An interpreter may be used to interpret the metadata file before it sent to the rendering engine. Neither the rendering engine nor the interpreter needs knowledge of the host application and provides support for arbitrary metadata driven UI. The metadata schema may include mechanisms to create custom controls for the UI; programmatically modify the UI controls by providing access to a code-behind assembly as well as support event handling for the UI controls.
