Abstract: Embodiments are directed to providing an application model to deploy and manage composite applications and to providing model-driven software coding assistance. In an embodiment, a computer system instantiates an application design interface that is configured to display composite application components and relationships between the components. Each component includes information specifying how communication is to be conducted with the component. The computer system accesses an application manifest that includes the components and component relationships of the application. The computer system displays the composite application's components and component relationships in the instantiated visual application design interface according to the application manifest.

Abstract: Described is a Web-enabled application that transmits or receives serialized messages and declaratively identifies another module of code to execute on a message either when received or prior to being transmitted. Briefly stated, a system embodies an infrastructure where a module of code associated with a Web service may be annotated with identifiers for other modules of code (“extensions”). When executed, the Web service code invokes the extension, which is configured to operate on an incoming or outgoing message. The extensions are configured to capture a stream of information related to the message, operate on the stream of information as programmed, and make the modified stream available for either serialization or deserialization.
