Abstract: Requesting security tokens with typed information. A method includes accessing at a client, information to allow the client to request a token for accessing functionality of a service. The method further includes sending a client request from the client to a token issuer in a token request. The client request includes the information and at least one of information defining the source of the information, proof of the source of the information; or usage information specifying how the information should be used.

Abstract: Methods, systems, and computer program products for processing network messages in a manner that simplifies messaging application logic. Processing layers of a messaging system architecture that may include a transport layer, a channel layer, a send/receive layer, a service/client layer, and potentially others, are aware of an End Point Reference (“EPR”) within a network message The transport layer retrieves message data from a message transport. The channel layer de-serializing the network message consistent with an underlying type system. The send/receive layer filters and dispatches the network message to messaging logic (other layers or application logic) based on the EPRs. The service/client message layer dispatches the network message to messaging application logic based on the EPRs.

Abstract: A messaging transport writer is provided that efficiently packages a massage and multiple message attachment streams into a single transport stream, based on a specified encapsulation format. For example, a packaging writer is provided that takes the message and multiple attachments and streams them directly into the single transport stream, without first coping them into a buffer prior to encapsulation. The encapsulation information is streamed into the transport stream on the fly, i.e., as the message and attachment streams are also being written to the transport stream.

Abstract: Described is a system and method for modifying a user-interface by applying a policy that is defined by an external party. The policy modifies the user-interface based on a user's context within the user-interface and prevents the user from performing certain actions. For example, in a software development environment, the user-interface is a user-interface provided by the software development environment and the certain actions that are prevented include adding inappropriate code to an application being developed in the software development environment. The policy may cause the software development environment to disable a menu that is associated with the inappropriate code. The policy may also modify the software development environment in a manner such that the developer is provided with active guidance if undesirable code is added to the application. The active guidance includes text being displayed that explains a reason for preventing the undesirable code within the application.
