1. News in WCF 4.0 Iaşi, 20 februarie 2010 Florin Cardaşim, www.rms.ro

2. Agenda

4. Hosting in IIS without .svc file… but for scenarios other than “common” WCF configuration is still a non-trivial task DEMO

5. Service Discovery WS-* WS-ServiceDiscovery SOAP-based protocol for dynamically discovering the location of service endpoints at runtime Adhocmode Direct client-service multicast messages over UDP Managed mode A discovery proxy “manages” the discoverable service endpoints

7. Search based on criteria (ex: contract name, version etc)

8. Services answer directly

9. Services may “announce” online/offline

10. ONLY on local subnet UDP multicast Client Services search answer Client Services Clients Services announce online/offline

12. Client: DynamicEndpointUdpDiscoveryEndpoint ICalculatorService net.tcp://…/CalculatorService/Guid Client Service

14. Client: DiscoveryClient, FindCriteriaasynchronously UdpDiscoveryEndpoint ICalculatorService net.tcp://…/CalculatorService/Guid Client Service

15. Demo: “Announcements” AnnouncementService Server: ServiceDiscoveryBehavior, UdpAnnouncementEndpoint Client: AnnouncementService, UdpAnnouncementEndpoint See also the “Configuration” sample Client UdpAnnouncementEndpoint Service CalculatorProxy ICalculatorService net.tcp://…/CalculatorService/Guid

18. Clients “ask” Disco Proxy

19. More flexible, reduces multicasts trafficClient Services Client Services Discovery Proxy Clients Services answer search announce online/offline

20. Demo: “DiscoveryProxy” AnnouncementEndpoint net.tcp://localhost:9021/Announcement DiscoveryProxy: DiscoveryProxy, DiscoveryEndpoint, AnnouncementEndpoint Service: ServiceDescoveryBehavior, AnnouncementEndpoint Client: DiscoveryClient, DiscoveryEndpoint DiscoveryEndpoint net.tcp://localhost:8001/Probe DiscoveryProxy ICalculatorService net.tcp://…/CalculatorService/Guid Client Service

24. Demo: Error handling WebFaultException, WebFaultException<T>

26. Load balancing

27. Protocol bridging

28. Content based routing for licensing, prioritization, versioning etcRouting Service One-way Request-reply Duplex Services Client Services Client Services Clients

29. Routing Service Supported communication patterns Filters

30. Demo: “HelloRoutingService” IMetadataExchangeEP Client connects to RouterService Calls are routed to ICalculatorEP based on the MatchAll filter The routing service has a proxy to the CalculatorService IRequestReplyRouterEP IMetadataExchangeEP RoutingService Client CalculatorService ICalculatorEP Internal Proxy

31. Demo: RouterBridgingAndErrorHandling Client connects to RouterService via HTTP Calls are routed to deadDestination based on the MatchAll filter deadDestination is not reachable so go to realDestination deadDestination IRequestReplyRouterEP RoutingService HTTP Client Internal Proxy realDestination CalculatorService TCP
