WCF

WCF programming model support 3 styles of programming :

1. Declarative programming, in which we can define attributes
2. Imperative programming, in which we work with the WCF object model in code
3. Configuration-based programming, in which we define behavior in application configuration files

Service programs: In it defines four element

1. Contract definitions: A servicehave at least one service contract, and it might contain multiple service contracts, data contracts, or message contracts.
2. Implementation code: The service contracts in a service need code to implement their service operations.
3. Hosting code: Some code is needed to create and start the service.
4. Endpoint definitions: One or more address "binding" contract endpoints must be declared.
