Introduction to WCF: A Comprehensive Guide for Efficient Communication

Explore the fundamentals of Windows Communication Foundation (WCF) and its applications in building robust communication services. This guide provides insights into WCF’s consistent interface for various communication protocols including TCP, HTTP, MSMQ, and Named Pipes. Learn about the ABCs of WCF: Address, Binding, and Contract, along with practical examples for service configuration. Understand how to host WCF services and leverage advanced functionalities such as RESTful services. Whether for cloud or on-premises applications, this guide has you covered.

  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
