Tulasi · Answer

HI  In WCF all services expose contracts. The contract is a platform-neutral and standard way of describing what the service does. WCF defines four types of contracts. 1. Service contracts : Describe which operations the client can perform on the service. 2. Data contracts : Define which data types are passed to and from the service. WCF defines implicit contracts for built-in types such as int and string but we can easily define explicit opt-in data contracts for custom types. 3. Fault contracts : Define which errors are raised by the service and how the service handles and propagates errors to its clients. 4. Message contracts : Allow the service to interact directly with messages. Message contracts can be typed or untyped and are useful in interoperability cases and when there is an existing message format we have to comply with Please mark the answer as Accepted if it helps you.
