WCF - In a Week
- 2. Name: Gnana Arun GaneshTitle: MVPhttp://arunmvp.blogspot.com/www.mugh.netWhat’s new in WCF4.0?
- 3. AgendaWhat’s new in WCF4.0?Simplified ConfigurationRouting ServiceREST ImprovementsDiscovery
- 4. WCF in a SlideOne-stop-shop for servicesConsistent object modelGreat “ility” features1st released with .NET Framework 3.0Single programming model that can be used for various kinds of communication
- 5. WCF GoalsUnificationUnification of Microsoft’s Distributed Computing Technologies
- 7. ABC’s of ServiceWCF SERVICEAddress: Where is the service? Binding: How do I communicate to the service?Contract: What can the service do for me? Endpoints: Addresses, Bindings, and Contracts!
- 8. ABC’s of ServiceBindings ship with WCF

- 10. Tool ImprovementsProductivity BreakthroughsAutomatically generated WCF clientThe ChallengeCreating and maintaining a test client for WCF services is time consuming and tedious.The SolutionVisual Studio 2008 includes a feature that inspects a WCF service and automatically generates a client for it. Because this client is automatically generated each time, it is always up to date.This client tools supports complex service contracts, so it is practical for even the most demanding WCF services.
- 11. Tool ImprovementsProductivity BreakthroughsWCF Performance ProfilingThe ChallengeServices are often created to be used in very demanding, high-traffic environments.The SolutionVisual Studio 2008 has been enhanced to include profiling WCF applications. Using this profiler, developers can pin point performance bottlenecks in their crucial services before they ever leave the development phase.

- 15. Protocol Mappings: Default bindingsYou can now specify your default binding per scheme <system.serviceModel> <protocolMapping> <add scheme="http" binding="wsHttpBinding" /> </protocolMapping>…DEFAULT:<protocolMapping> <add scheme="http" binding="basicHttpBinding"/> <add scheme="net.tcp" binding="netTcpBinding"/> <add scheme="net.pipe" binding="netNamedPipeBinding"/> <add scheme="net.msmq“ binding="netMsmqBinding"/> </protocolMapping>

- 17. WCF – Building RESTful servicesREST/URI/HTTP VerbsREST defines an architectural style based on a set of constraints for building things the “Web” way. URI / Segment of a URI map to Application LogicHTTP GET – View It OperationsHTTP <Other> - Do it operations
