1. Required Slide SESSION CODE: DEV202 Implementing RESTful Services Using the Microsoft .NET Framework Ron Jacobs Technical Evangelist Microsoft Corporation http://blogs.msdn.com/rjacobs

2. Experience Share, explore, question my world With others When and how I want Even right now On whatever device I have at hand

3. How do we move from a PC oriented experience to a multi-device experience? question

4. Services Drive Experiences data

5. Services Drive Experiences Services

6. The Web of Services should work the way the Web of Pages works

7. WCF Programming Model SOAPServices 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, Open Data Protocol,…)

9. Model

10. Service publicclassConference: DataService<ConferenceDataEntities> { // This method is called only once to initialize service-wide policies. publicstaticvoidInitializeService(DataServiceConfigurationconfig) { config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; } }

11. Data Services demo

12. Implications • Fast and Easy • REST over Model (backed by Database) • Also supports Services • Power to the caller

13. Constrain publicclassConference: DataService<ConferenceDataEntities> { // This method is called only once to initialize service-wide policies. publicstaticvoidInitializeService(DataServiceConfigurationconfig) { config.SetEntitySetAccessRule("*", EntitySetRights.AllRead); config.DataServiceBehavior.MaxProtocolVersion = DataServiceProtocolVersion.V2; config.SetEntitySetPageSize("Sessions", 10); config.SetEntitySetPageSize("Speakers", 5); } }

14. Route privatevoidRegisterRoutes() { DataServiceHostFactory factory = newDataServiceHostFactory(); RouteTable.Routes.Add( newServiceRoute("Conference", factory, typeof(Conference))); }

17. Three Steps to build a WebHttp Service

18. Resource publicclassSessionData { publicint ID { get; set; } publicstring Title { get; set; } publicDateTime? Date { get; set; } publicstring Speaker { get; set; } }

19. Three Steps to build a WebHttp Service

20. Resource URI

21. Three Steps to build a WebHttp Service

22. Web HTTP Services demo

23. Step 1 – Create Service

24. Step 2 – Implement Service

25. Step 3 – Attribute for WCF

26. Step 3 – Attribute for WCF HTTP GET = “~/Sessions/GetSession?id=123”

27. Step 3 – Attribute for WCF HTTP GET = “~/Sessions/123”

28. Step 3 – Attribute for WCF HTTP GET = “~/Sessions?start=5&count=7”

29. Step 4 – Add Routes publicclassGlobal : System.Web.HttpApplication { voidApplication_Start(object sender, EventArgs e) { RegisterRoutes(); } privatevoidRegisterRoutes() { WebServiceHostFactory factory = newWebServiceHostFactory(); RouteTable.Routes.Add( newServiceRoute("Sessions", factory, typeof(SessionService))); } } No .SVC file!

30. Step 5 – Configure <system.serviceModel> <standardEndpoints> <webHttpEndpoint> <standardEndpoint automaticFormatSelectionEnabled="true" helpEnabled="true" /> </webHttpEndpoint> </standardEndpoints> <serviceHostingEnvironmentaspNetCompatibilityEnabled="true" /> </system.serviceModel>
