Where in Keith Elder explained major differences between WCF (Windows Communication Foundation) and Web Services with real time example - aircraft analogy. It is really great post. I saw below mentioned Power point presentation of WCF posted by same author : http://keithelder.net/Presentations/DemystyfyingWCF/DemystifyingWindowsCommunicationFoundation.ppt This PPT explains basics of WCF nice. 2. http://www.techbubbles.com/wcf/wcf-vs-aspnet-web-services/ Where in blogger explained major differences between WCF (Windows Communication Foundation) and Web Services in terms of Serialization.
