  4. Extending the .NET Framework WCF

  5. The WinFX Vision WINFX • Increase developer productivity • Improve application security, deployment and manageability • Leverage existing developer skills • Enabled by a new programming model, WinFX • Built on the .NET Framework • Easily extend Win32 applications

  6. The Shift to Service Orientation Process-oriented Built for change Incrementally built and deployed Loosely coupled Connected Systems Function-oriented Built to last Prolonged development cycles Tightly coupled Application silos

  7. Distributed Stacks Today ServicesInteroperableASP.NET Infrastructure ComponentsTransactionsCOM+ Infrastructure Objects Extensible CLR Infrastructure QueuingReliable MsgMSMQ Infrastructure • Each stack has different strengths, target scenarios • Customers want to mix and match, compose • Reliable services • Interoperable transactions WCF

  8. Challenges How do I ensure reliable, universal connectivity in the face of network failures? How do I support rich authentication types, including federated identity? Which programming model should I use? How do I ensure interoperability with other platforms? How do I make my distributed applications less fragile? How do I make them “service-oriented?”

  9. Unifies Distributed Technology Stacks • Designed for On-Machine, Cross-Machine, and Cross-Internet Scenarios Unification • Broad support for WS-* specifications • Compatible with existing MS distributed application technologies Interoperability • Enables Development of Loosely-Coupled Services • Config-Based Communication Service- Orientation Windows Communication Foundation “The unified programming model for rapidly building service-oriented applications on the Windows platform”

  10. Unification WCF .NET Remoting ASMX Interop with other platforms Extensibility Location transparency Attribute- Based Programming Message- Oriented Programming WS-* Protocol Support Enterprise Services System.Messaging WSE

  11. ABC’s of Indigo!!!! WSDL Client Service A B C C B A A B C A B C B B Address Where? Binding How? Contract What?

  12. Bindings

  13. WCF extends the .NET Framework • Services are built in Visual Studio 2005 using any .NET programming language • Intelligent code editing • Debugging • Deployment

  14. Side-by-side co-existence with existing distributed technologies Seamless communication with applications built on existing technologies Smooth upgrade of existing code to WCF ASMX ASMX ES WSE3 ASMX Investment Protection
