Question

Here is my edmx diagram.

I am trying to use

UserEntity.users.ToList<user>();

This provides me with a complex object of User s that contain user_groups , but I can't seem to find the Group information. My understanding is that EF is supposed to abstract out the join table and provide me with direct access to the Group information. Please note I am coming from cakephp and hoping for a similar style result!

Edit: Model Code

 public static class UserModel
    {
        static UserEntities dataContext = new UserEntities();

        public static void CreateUser(user _newUser)
        {
            dataContext.users.AddObject(_newUser);
            dataContext.SaveChanges();
        }

        public static List<user> GetAllUsers()
        {
            return dataContext.users.ToList<user>();
        }
    }

Answer 1

There is one to many relationship between users and user_group , so you may select a single user_group from users and against that you will get group.

var result = users.user_group.FirstOrDefault().group;

The Navigation property user_group in users will have a collection of user_group objects, you may select First or anything based on your requirement and then select group from there.
