C# - MVC - Loose coupling and dependency injection and DI Container

Hello, i need to create a design pattern using

1 - Loose coupling
2 - dependency injection
3 - DI Container

I'm already write something for apply the DI, but i'm have a problem and i can't understand why??

please i need to help , let see my codes :

Class User :

public partial class User
    {
        public int Id { get; set; }

        public string Username { get; set; }

        public string Pwd { get; set; }

        public string Email { get; set; }

        public DateTime? TransDate { get; set; }
    }
}

Model Context :

    public partial class FavSolutinsModel : DbContext
    {
        public FavSolutinsModel()
            : base("name=FavSolutinsModel")
        {
        }

        public virtual DbSet<User> Users { get; set; }

}

Interface :

namespace FavSolutions.Interfaces
{
    public partial interface IFavSolutions
    {
        List<User> GetAllUsers();

    }
}

Services Or Respiratory :

namespace FavSolutions.Services
{
    public class FavSolutionsServices : IFavSolutions
    {
        private FavSolutinsModel _context = new FavSolutinsModel();
        private IFavSolutions _favServices;
        public FavSolutionsServices(IFavSolutions favServices)
        {
            _favServices = favServices;
        }
        public List<User> GetAllUsers()
        {
            return _context.Users.ToList();
        }
    }
}

Finally , Controller :

namespace FavSolutions.Controllers
{
    public class UsersController : Controller
    {
        private IFavSolutions _favServices;
        public UsersController(IFavSolutions favServices)
        {
            _favServices = favServices;
        }
        public ActionResult Index()
        {
            var model = _favServices.GetAllUsers();
            return View();
        }
    }
}
