After running this code I find no entrys in my database. I receive no errors from the code.

Does anyone know what I mite be doing wrong ?

PeopleEntities1 db = new PeopleEntities1();


            Person roger = new Person() 
            {  
                age = 25,
                firstname = "Roger", 
                lastname = "Rabbit", 
                location = "Canada", 
                job = "freelance", 


            };

            db.AddToPeople(roger);
            db.SaveChanges(true);
