I can't find the DataContract attribute

I'm trying to make an application with Indigo, there is the ServiceContract and OperationContract,
but I can't find the DataContract attribute nor the DataMember.

Thanks.

To get the DataContract and DataMember attributes, reference System.Runtime.Serialization.dll
