[DataContract] attribute specifies the data, which is to serialize (in short conversion of structured data into some format like Binary, XML etc.) and deserialize(opposite of serialization) in order to exchange between the client and the Service.

Why DataContract is used in WCF?

A data contract is a formal agreement between a service and a client that abstractly describes the data to be exchanged. That is, to communicate, the client and the service do not have to share the same types, only the same data contracts.

When to specify XML namespace in WCF 1?

When posting XML data to a Windows Communication Foundation (WCF) web service 1, you need to specify the XML namespace of the data sent in the entity-body of your HTTP POST. This lets WCF know how to deserialize the input you’ve sent. By default, WCF maps the namespace to:
