Vision and Goals

Simplify RIA developmentn-tier is hard, and un-natural

Bring ASP.NET/RAD-style productivity to RIA development

Focus on end-to-end scenarios and solutions

Value Propositions

Focus on data in an end-to-end mannerA unified story for client and server developmentA prescriptive framework that targets key scenarios, and leads the common developer to a pit of success

End-to-End Data

Beyond accessing and editing rowsApp-specific custom operationsData shaping (sorting, paging, and filtering)Rules (validation, authorization, and conflict handing)Batching and offline

Abstract

Learn how Microsoft is simplifying the traditional n-tier application pattern by bringing together ASP.NET and Silverlight, and hear about an application framework that allows you to tap into the synergy of .NET on the server and on the client. Learn about patterns for working with data, implementing reusable and independently testable application logic, and application services that readily scale with growing requirements.
