Exposing Methods in a Datacontracts will not make sense.DataContracts can be applied only to the state of your objects or in otherwords member fields of the class.Methods are not states but rather they are agents of state change.

And you should not have a OperationContract inside the DataContract here is why

Can a WCF data contract contain a WCF operation contract inside it? Why?

As people said in Adding methods to DataContract objects for WCF

DTOs that are decorated as DataContract classes are real objects. They can have methods in them, but since a data contract describes the data which is communicated the methods are not part of the serialization process.
