We can get really compact if we use AutoMapper.

Bootstrap the mapper in your repository:

Mapper.CreateMap();

Then it's pretty simple (and there's nothing wrong with returning IEnumerable).

public IEnumerable Get()
{
    using (var db = new MyContext())
    {
        return (from u in db.Users
                orderby u.FirstName
                select Mapper.Map(u)).AsEnumerable();
    }
}
