AgendaRIA Applications TodayBuilding Data Driven ApplicationsSilverlight 3.0 RIA Services

ObjectiveIn this session, we will talk about how tough it is to build data driven RIA Applications using today’s technologies.We will then see how the Silverlight 3.0 RIA Services addresses these problems by creating a comprehensive architecture pattern for developing Rich Interactive Applications.

RIA Applications todayThe pains and the travails of developing RIA Apps

ASP.NET and Ajax development is very time consumingSilverlight development is not better

Key focus : Developer productivityASP.NET MVC introduces an easier model for developing data driven applications

Taking ASP.NET MVC forward

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
