  2. From Objects to Services Object-Oriented Polymorphism Encapsulation Subclassing 1980s Component-Based Interface-based Dynamic Loading Runtime Metadata 1990s Service-Oriented Message-based Schema+Contract Binding via Policy 2000s

  3. WCF Unified framework for rapidly building service-oriented applications

  4. WCF Microsoft Innovation & Practice Team, MSCoE

  5. Message Services and Clients Client Service Message

  6. Endpoint Endpoint Endpoint Endpoints Client Service Message

  9. C C C B B B A A A A+B+C Client Service Message Address Binding Contract (Where) (How) (What)

  10. Address (A) Every service is associated with a unique address.

  11. Address (A)

  12. Address (A)

  13. Address (A)

  14. Address (A)

  28. Binding (B) Binding Classes

  29. Binding (B) Configuring Binding <endpoint address="Calculator" bindingSectionName="basicProfileBinding" bindingConfiguration="Binding1" contractType="ICalculator" /> <bindings> <basicProfileBinding> <binding configurationName="Binding1" hostnameComparisonMode="StrongWildcard" transferTimeout="00:10:00" maxMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" </binding></basicProfileBinding></bindings>

  40. Creating End Point

  41. Defining Endpoints <?xml version="1.0" encoding="utf-8" ?> <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <system.serviceModel> <services> <service serviceType="CalculatorService"> <endpoint address="Calculator" bindingSectionName="basicProfileBinding" contractType="ICalculator" /> </service> </services> </system.serviceModel> </configuration>

  42. Multiple End Point

  43. Multiple End Point • <endpointaddress="http://localhost:8890/a" binding="wsHttpBinding" contract="HotsingSamples.IService1"/> • <endpointaddress="http://localhost:8000/b" binding="basicHttpBinding" contract="HotsingSamples.IService1"/> • <endpointaddress="net.tcp://localhost:8001/c" binding="netTcpBinding" contract="HotsingSamples.IService1"/>

  44. Hosting

  45. Creating WCF Service Defining .Net service interface to serve as the Service contract Implement Service Contract in .Net class as Service type and configure its behavior Configure the End Point where service will expose , by specifying A,B,C Host Service type in application using WCF hosting infrastructure At client side ,By using description of target End Point create PROXY. And write code against this Proxy.

  46. WCF basic task cycle

  47. Transport Encoder Protocol(s) Transport Encoder Protocol(s) Architecture: Messaging Runtime Service Contract andBehaviors Client Dispatcher Binding Address
