  1. Intro to WCF From the beginning and uses Steve Maier @YsFred4 http://strugglingthru.net/ steve.maier@gmail.com AppRochester

  2. Before WCF • Sockets • Named Pipes • TCPIP • HTTP • MSMQ • Everything had a different API that you had to learn. • Switching from one to another was not simple.

  3. With WCF we get… • Consistent interface for all communication • TCP • HTTP • MSMQ • Named Pipes • Peer-to-Peer • XML configuration to define • Endpoints, binding, behaviors, etc • Can use code behind instead of XML

  4. ABCs of WCF • A – Address • the location of the service and the transport protocol used to communicate with the service • B – Binding • How do I talk to the service • Basic binding, TCP binding • C – Contract • a platform-neutral and standard way of describing what the service does

  5. Examples of ABCs of WCF • A – Address • net.tcp://localhost:8081/SpeakerService • http://localhost:49868/SpeakerService.svc • http://localhost:57402/TaPService.svc?wsdl

  6. Examples of ABCs of WCF • B – Binding • netTcpBinding • netPeerTcpBinding • basicHttpBinding (SOAP compatible) • mexHttpBinding • mexHttpsBinding • netNamedPipeBinding • msmqIntegrationBinding

  7. Examples of ABCs of WCF • C – Contract • [ServiceContract]     publicinterfaceISpeakerService{ [OperationContract]         SpeakerInfoGetNextSpeaker();          [OperationContract]         voidAddSpeaker(SpeakerInfonewSpeaker);          [OperationContract]         IEnumerable<SpeakerInfo> GetAllSpeakers();     }

  8. Service Configuration Editor • Windows SDK Tools • Allows editing of the app.config to add services • demo

  9. Service Configuration Editor (cont.)

  10. WCF is just a Web Service?

  11. Hosting WCF Services • WCF Services can be hosted in many different things. • IIS / Azure (ASP.NET project) • Apps • Windows Services

  12. Using WCF for a Singleton • WCF can also be used to implement the Singleton pattern • Yes it is overkill, but it will work • Demo

  13. WCF as a Web Service • Hosted with IIS on a server or in the cloud • ASP.NET projects • Sync (default) or Async • Demo

  14. WCF Goes RESTful • NuGet package from MS for WCF REST services • Demo

  15. WCF Futures • Web API • http://wcf.codeplex.com/ • Way to configure wcf for web messaging, even form posts • Simplified setup • NugetWebApi.All • Jquery Support • JSON
