Automatic class generator

How do I get an entity in the DB (Oracle) and generate a class on my system that represents that entity?

Ex: I have this entity

  

Customer

     

ID int primary key

     

Name varchar (100)

And now with the tool it already generates this:

using System;
using System.Data;

namespace meu_projeto.meu_folder.classes
{
public class Cliente{

    public int ID { get; set; }
    public string name { get; set; }

  }
}

That is, generating a POCO class based on a DB entity (Oracle), how do I do it?

I'm using WPF for this.
