Agenda
RIA Applications Today
Building Data Driven Applications
Silverlight 3.0 RIA Services
Objective
In 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 consuming
Silverlight 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 manner
A unified story for client and server development
A 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 operations
Data shaping (sorting, paging, and filtering)
Rules (validation, authorization, and conflict handing)
Batching and offline
