public class User
{
     public int Id {get;set;}
     public List<int> Permissions {get;set;}

What should I do for this work as an one-many relashionship?

Answer 1

Create a Permission type:

public class User
{
     public int Id { get; set; }
     public ICollection<Permission> Permissions { get; set; }
}

public class Permission
{
   public int Id { get; set; }
   public int Value { get; set; }
}
