This add-on enables the Astoria client library to run inside Microsoft Silverlight applications

This add-on extends the CTP by introducing a version of the client library that can run inside the Microsoft Silverlight 1.1 environment. This version of the library also includes an extension to the API that allows developers to execute queries asynchronously, a more natural interaction model for a web-centric application.
