What is WCF?
WCF stands for Windows Communication Foundation (WCF) and is considered as the Microsoft Service-Oriented Architecture (SOA) platform for building distributed and interoperable applications. WCF unifies ASMX, Remoting, and Enterprise Services stacks and provides a single programming model. WCF services are interoperable and supports all the core Web services standards. WCF services also provide extension points to quickly adapt to new protocols and updates and integrates very easily with the earlier microsoft technologies like Enterprise Services, COM and MSMQ.

What is WSDL?
What is the role of WSDL in WCF?
WSDL stands for Web Service Description Language. The WCF service exposes the WSDL document for the clients, to generate proxies and the configuration file. The WSDL file provides the following information for the consumers of the WCF service.
1. Provides the information about the service contract and operations available.
2. Provides the information about all the end points exposed by the WCF service.
3. Provides the information about the messages and types that can be exchanged between the client and the WCF service.
4. WSDL also provides any information about the policies used.

3 things WCF Services must have
What are the 3 things that a WCF Services end point must have?
Address - The address where the WCF Service is hosted.
Binding - The binding that decides the protocol, message encoding and security to use. Binding also decides whether to use reliable messaging and transaction support.
Contract - The service contract defines what service operations are available to the client for consumption.
So the Address(A), Binding(B) and Contract(C) are called as the ABC of the service end point.
