When should I use datacontract and when messagecontract in WCF

Question

On what basis should we decide whether we need to create a dataContract or MessageContract for my WCF services.

I know that when we need more control over SOAP, we use MessageContract.

Secondly, I saw some code in which a DataContract is displayed through MessageContract.Whats its use.

Please provide some real life scenarios.
