Entity framework with Web Service

I am developing a project while my internship.In this project I am taking data from database and making operations on them with services. Then I send them to the client.

My problem : I made a wcf-linq service but I don't know how can I develop a similar entity framework with WEB SERVICE .

Can anyone send me an example of Entity framework With web service.(In .Net Framework 4 , there is no web service project. It's only available in 3.开发者_如何学C5 )

Thank you in advance

I have solved it by creating a webservice project and writing my methods under [WebMethod]s. I thought it has interface like wcf but it has not.
