Hi,
First understand about bindings and endpoints in wcf.
1) see about basichttpbinding and webhttpbinding
2) call a simple method using both these bindings.
3) see about behaviour configuration.
4) DataContract and DataMember
5) ServiceContract and OperationContract
For better understanding first do a sample using webhttpbinding.
next you will learn yourself and gets idea about all those above.
I think the below links will be helpful for you...
