  1. CL07 Mastering WCF RIA Services Dinesh Kulkarni Program Manager Developer Division Microsoft Corporation

  2. Agenda • WCF RIA Services in context • A look “under the hood” • Using RIA Services effectively

  3. Agenda • WCF RIA Services in context • A look “under the hood” • Using RIA Services effectively

  4. RIA Services in n-tier applications Trust Boundary Framework, tools and services with prescriptive pattern for n-tier applications Web Service Data Access Layer (DAL) App Logic App Logic View Database

  5. Windows Communication Foundation (WCF) Programming Model Core Services Web HTTP Services Data Services RIA Services Workflow Services Service Model Data Contract Service Contract Service Behavior Channel Model Formats (Atom, JSON, XML,…) Transports (HTTP, TCP, …) Protocols (SOAP, HTTP, OData, …)

  6. Design principles • End-to-end view of an application: framework, pattern, tooling and services • Prescriptive approach to app logic • DAL-neutral and targets multiple presentation technologies

  7. Data access & presentation neutral App Logic XML,JSON, Binary

  8. Agenda • WCF RIA Services in context • A look “under the hood” • Using RIA Services effectively

  9. Agenda • WCF RIA Services in context • A look “under the hood” • Design-time view • Run-time view • Services • Using RIA Services effectively

  10. Agenda • WCF RIA Services in context • A look “under the hood” • Design-time view • Run-time view • Services • Using RIA Services effectively

  11. Design-time view Solution (Application) Client project Server project Entities Entities Data Access Layer (DAL) Views DomainService DomainContext Build, reflect & code-gen

  12. Design-time view Demo Writing app logic and using generated code

  13. Code gen recap … Server project Client project Generated code DishViewDomainContext: DomainContext class Plate: Entity EntityQuery<Plate> GetPlatesQuery(…) CreateEntitySet<Plate>(EntitySetOperations.Edit) Restaurant.FeatureOnSite(); [EnableClientAccess()] DishViewDomainService: DomainService IQueryable<Plate> GetPlates(…) void UpdatePlate(Plate p) void FeatureOnSite(Restaurant r)

  14. Agenda • WCF RIA Services in context • A look “under the hood” • Design-time view • Run-time view • Services • Using RIA Services effectively

  15. Run-time view (entity lifecycle) Application Silverlight Web server DomainContext DomainService Data Access Layer (DAL) Views Query Entities Entities Submit Submit Results Results Load context.Load(GetRestaurantsQuery(…).Skip(10).Take(10)) context.SubmitChanges() GetRestaurants(…).Skip(10).Take(10) Submit(changeSet)

  16. Run-time view Demo Query w/ LINQ & CUD w/ unit of work

  17. Summary • Entity lifecycle • Query • Unit of work: insert, delete, update, custom update • DomainContext • Bindable collections, entities • Async support • Id management, change tracking • DomainService • CRUD support • Option of open service layer with WCF

  18. Agenda • WCF RIA Services in context • A look “under the hood” • Design-time view • Run-time view • Services • Using RIA Services effectively

  19. Services • Authentication • Roles • User profile • All integrate w/ ASP.NET infrastructure

  20. Services Demo Authentication and roles

  21. Summary • Authentication & roles • Declarative: class / method-level • Integrated into Query / Submit processing

  22. Agenda • WCF RIA Services in context • A look “under the hood” • Using RIA Services effectively

  23. Using RIA Services effectively Do Don’t Deploy with anon access Expose non-essential entities/ operations or allow free-form access to data Use a single large DomainService class • Require authentication / roles • Authenticate w/ https • Utilize query composition • Filter, sort, page • Consider custom update • Factor into multiple DomainService classes / libraries • Handle errors on server • Use declarative validation

  24. Call to action • Try RIA Services bits • Beta on .NET 3.5 SP1/ VS 2008 / Silverlight 3 • Preview on Dev10 / Silverlight 4 (this will evolve into V1 RTW) • Give us feedback and join us on forum • Home page • http://silverlight.net/riaservices/
