Silverlight & WCF RIA
This document discusses .NET RIA Services and SQL Data Services. It begins with an introduction to Class-A, a Microsoft development training company, and the presenter Dennis van der Stelt. The agenda is then outlined, covering SQL Data Services, .NET RIA Services, and a demo. SQL Data Services are explained in more detail and code examples are provided. .NET RIA Services are then discussed, covering the vision and goals of simplifying RIA development and bringing ASP.NET productivity to the client. The multi-tier application model and an example demo are presented before closing with questions.

- 11. End-to-End Data • Beyondaccessing and editing rows – App-specific custom operations – Data shaping (sorting, paging, filtering) – Rules (validation, authorization, conflict handing) – Batching and offline
