# What are the ABC of a WCF service?

**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.\
