5. WCF RIA Services Overview Entities Validation Service Access • Simplifies building N-tier Line of Business (LOB) applications • Highly dependent on push pull of data • Can use for non-CRUD operations as well • Architecture and tools for building the glue code between the client and the back end • Streamlined pipeline for data and operations between client and server • Clients: Silverlight & ASP.NET • Future releases: ASP.NET client side JavaScript (WCF JQuery) WCF RIA Services Presentation Services Entities Validation Business Logic Data Access DB

6. The Benefits Built on / Simplifies WCF Flexible Data Sources Client Query / Updates Change Tracking Security Shared Validation

7. What do you need? • Silverlight Tools for Visual Studio 2010 • RTW Core bits (v1) • RIA Services Toolkit • Other endpoint types (SOAP, JSON) • ASP.NET support for consuming domain service in process • WCF RIA Services SP1 (shipped with VS 2010 SP1) • Complex types support for child objects • Sharing entities across domain services • Better data binding to client collection types • Various other improvements

8. Coming Soon in SP2 • MVVM Support • EF Code First • DateTimeOffset • Support for SL5

10. Application Architecture Client App • Web project • Silverlight host • Domain Services • Client project • Generated code • DomainContext classes • One per domain service View/ViewModel DomainContext + Entities Server Host DomainService Data Access + Entities DB

11. Querying and Updating Data With RIA Services Brian Noyes Chief Architect, IDesign demo

12. Entities • The data you pass between client and service • Entity Framework • LINQ to SQL • POCO

13. Query Operations • Return collections or individual objects • Support deferred execution through IQueryable<T> • Load through DomainDataSource • Load programmatically with DomainContext

14. Update Operations • Entity changes are cached in the client DomainContext • Contains an EntityContainer that tracks changes • Sent as a batch to the service • Including original version for optimistic concurrency • Service executes batch, calling Insert, Update, and Delete methods with one entity per method call • Returns server updated entities (i.e. PK Ids) and refreshes the client cache
