Answer 1

Please correct me if I am wrong, but I think I achieved that goal with this code:

//only for forbiding the calls of constructors without parameters on derived classes
public class UnconstructableWithoutArguments
{
    private UnconstructableWithoutArguments()
    {
    }

    public UnconstructableWithoutArguments(params object[] list)
    {
    }
}
