Basics Of WCF

Main components of WCF are :
1. EndPonits
2. Binding
3. Contract

A service is a construct that exposes one or more endpoints, each of which exposes one or more service operations.
The endpoint of a service specifies an address where the service can be found, a binding that contains the information that a client must communicate with the service, and a contract that defines the functionality provided by the service to its clients.

Windows Communication Foundation (WCF) enables applications to communicate whether they are on the same computer, across the Internet, or on different application platforms.

The Basic Tasks

The basic tasks to perform are, in order:

1. Define the service contract. A service contract specifies the signature of a service, the data it exchanges, and other contractually required data.

2. Implement the contract. To implement a service contract, create the class that implements the contract and specify custom behaviors that the runtime should have.

3. Configure the service by specifying endpoint information and other behavior information.

4. Host the service in an application.

5. Build a client application.
