WCF applications have three basic components: a WCF service assembly, a WCF service host, and WCF clients. The ABCs of WCF are the address, binding, and contract. The address specifies where to find the service. The binding defines the transport protocol, encoding, and security for communication. The contract describes what the service does through service contracts, data contracts, and fault contracts.
