What's new in WCF 4.0

1. WCF 4.0 Eyal Vardi CEO E4D Solutions LTD Microsoft MVP Visual C# blog: www.eVardi.com

3. Simplified Configuration

4. Simplified Configuration using ( var host = new ServiceHost ( typeof ( CalculatorService ) , new Uri ( &quot;http://localhost:1234/Service&quot; ) , new Uri ( &quot;net.tcp://localhost:4321/Service&quot; ) ) ) { host.Open(); Console .WriteLine( &quot;The service is ready.&quot; ); Console .WriteLine( &quot;Press <ENTER> to terminate service.&quot; ); Console .ReadKey(); host.Close(); } The service is open with default binding & behaviors

5. Explicitly & Default Endpoints using ( var host = new ServiceHost ( typeof ( CalculatorService ) ) ) { host.AddDefaultEndpoints(); host.Open(); } < services > < service name = &quot; CalculatorService &quot; > < host > < baseAddresses > < add baseAddress = &quot; http://localhost:1234/Service &quot; /> < add baseAddress = &quot; net.tcp://localhost:4321/Service &quot; /> </ baseAddresses > </ host > </ service > </ services > Config File Default Endpoint

6. Default Endpoint In WEB

7. Default Profile < bindings > < basicHttpBinding > < binding maxReceivedMessageSize = &quot; 9999999 &quot; > < readerQuotas maxArrayLength = &quot; 9999999 &quot; /> </ binding > </ basicHttpBinding > </ bindings > < services > < service name = &quot; CalculatorService &quot; > < host > < baseAddresses > < add baseAddress = &quot; http://localhost:1234/Service &quot; /> < add baseAddress = &quot; net.tcp://localhost:4321/Service &quot; /> </ baseAddresses > </ host > </ service > </ services > No Name !!! Default profile for BasicHttpBinding

8. Protocol Mapping < protocolMapping > < add scheme = &quot; http &quot; binding = &quot; basicHttpBinding &quot; /> < add scheme = &quot; net.tcp &quot; binding = &quot; netTcpBinding &quot; /> < add scheme = &quot; net.pipe &quot; binding = &quot; netNamedPipeBinding &quot; /> < add scheme = &quot; net.msmq &quot; binding = &quot; netMsmqBinding &quot; /> </ protocolMapping > < services > < service name = &quot; CalculatorService &quot; > < host > < baseAddresses > < add baseAddress = &quot; http://localhost:1234/Service &quot; /> < add baseAddress = &quot; net.tcp://localhost:4321/Service &quot; /> </ baseAddresses > </ host > </ service > </ services >

9. Protocol Mapping < protocolMapping > < add scheme = &quot; http &quot; binding = &quot; wsHttpBinding &quot; bindingConfiguration = &quot; wsHttpBinding &quot; /> </ protocolMapping > < services > < service name = &quot; CalculatorService &quot; > < host > < baseAddresses > < add baseAddress = &quot; http://localhost:1234/Service &quot; /> < add baseAddress = &quot; net.tcp://localhost:4321/Service &quot; /> </ baseAddresses > </ host > </ service > </ services >

10. Simplified Configuration

12. File-less Activation

14. Standard Endpoint Setting < service name =&quot;HelloService&quot;> < endpoint kind =&quot;udpDiscoveryEndpoint&quot; endpointConfiguration =&quot;MyEndpointSettings&quot; /> </ service > < standardEndpoints > < udpDiscoveryEndpoint > < standardEndpoint name =&quot;MyEndpointSettings&quot; multicastAddress =&quot;soap.udp://239.255.255.252:3704&quot; maxResponseDelay =&quot;00:00:02&quot;> < transportSettings duplicateMessageHistoryLength =&quot;2048&quot; maxPendingMessageCount =&quot;5&quot; maxReceivedMessageSize =&quot;8192&quot; maxBufferPoolSize =&quot;262144&quot;/> </ standardEndpoint > </ udpDiscoveryEndpoint > </ standardEndpoints >

16. Standard Endpoint

17. Service Discovery

18. Why We Need Discovery?

19. Async WCF Services

20. WS – Discovery Service Opened Client Target Service Client Client Target Service Target Service Hello

21. WS – Discovery Client Look for Service Client Target Service Client Client Target Service Target Service Probe

22. WS – Discovery Service Return Match Message Client Target Service Client Client Target Service Target Service Probe Match

23. WS – Discovery Service Closed Client Target Service Client Client Target Service Target Service By

24. Multicast, Broadcast & Unicast Multicast Broadcast Unicast

25. WCF With Discovery Server Side Normal endpoints with EndpointDiscoveryBehavior Discovery endpoint with ServiceDiscoveryBehavior Target Service

26. WCF With Discovery Server Side < system.serviceModel > < service name =&quot;HelloService&quot;> < endpoint address = &quot;net.tcp://localhost/&quot; binding = &quot;netTcpBinding&quot; contract = &quot;ICalculator&quot; /> < endpoint kind = &quot; udpDiscoveryEndpoint &quot; /> </ service > </ behaviors > < serviceBehaviors > < behavior > < serviceDiscovery /> </ behavior > </ serviceBehaviors > </ behaviors > </ system.serviceModel >

28. Basic Discovery

31. Dynamic Endpoint

32. Discovery Announcements < service name =&quot;HelloService&quot;> ... < endpoint name =&quot;udpDiscovery“ kind =&quot;udpDiscoveryEndpoint&quot;/> </ service > ... < serviceBehaviors > < behavior > < serviceDiscovery > < announcementEndpoints > < endpoint name = &quot; udpAnnouncement &quot; kind = &quot; udpAnnouncementEndpoint &quot; /> </ announcementEndpoints > </ serviceDiscovery > </ behavior > </ serviceBehaviors > Server Side:

33. Discovery Announcements var announcementService = new AnnouncementService (); announcementService.OnlineAnnouncementReceived += OnOnlineEvent; announcementService.OfflineAnnouncementReceived += OnOfflineEvent; using ( var host = new ServiceHost ( announcementService ) ) { host.AddServiceEndpoint( new UdpAnnouncementEndpoint () ); host.Open(); ... } Consumers Side:

34. Discovery Announcements

35. Announcement Data

40. Discovery Proxy

43. Routing Services

45. Router Service Architecture Server C Server C Server B Client Router Service Filter Tables Filters Service A Service B Service C

46. Router Endpoints & Contracts < service name = &quot; System.ServiceModel.Routing.RoutingService &quot; > < endpoint name = &quot;reqReplyEndpoint &quot; address = &quot;&quot; binding = &quot; basicHttpBinding &quot; contract = &quot; System.ServiceModel.Routing.IRequestReplyRouter &quot; /> </ service >

48. Message Filter Compares the &quot;To&quot; & Headers address to the endpoint address Compares the incoming &quot;Action&quot; value against the actions on the contract

49. Message Filter Compares the &quot;To&quot; & Headers address to the endpoint address Compares the incoming &quot;Action&quot; value against the actions on the contract < filters > < filter name =&quot;addFilter&quot; filterType =&quot;XPath&quot; filterData =&quot;...&quot; > < filter name =&quot;addFilter&quot; filterType =&quot;Action&quot; filterData =&quot;...&quot; > </ filters >

50. Filtering architecture

52. Routing Services

56. Serialization Improvements

59. [ ServieContract ] public intrface IMedia { [ OperationContract ] Media GetMedia( Media media ); } [ DataContract ] public class Media { ... } [ DataContract ] public class DVD : Media { ... } [ DataContract ] public class CD : Media { ... } < Envelope > < Header > < Action >E4D/IMedia/GetMedia</ Action > </ Header > < Body > < GetMedia > < media type =&quot;CD&quot;> < Name>Madona </ Name > < Type>CDWR </ Type > </ media > </ GetMedia > </ Body > </ Envelope >

65. Web Http Programming
