Is Inheritance really needed?

Question

I must confess I\'m somewhat of an OOP skeptic. Bad pedagogical and laboral experiences with object orientation didn\'t help. So I converted into a fervent believer in Visua

In the following, inheritance is used to present a particular property for all of several specific incarnations of the same type thing. In this case, the GeneralPresenation has a properties that are relevant to all "presentation" (the data passed to an MVC view). The Master Page is the only thing using it and expects a GeneralPresentation, though the specific views expect more info, tailored to their needs.

   public abstract class GeneralPresentation
    {
        public GeneralPresentation()
        {
            MenuPages = new List();
        }
        public IEnumerable MenuPages { get; set; }
        public string Title { get; set; }
    }

    public class IndexPresentation : GeneralPresentation
    {
        public IndexPresentation() { IndexPage = new Page(); }
        public Page IndexPage { get; set; }
    }

    public class InsertPresentation : GeneralPresentation
    {
        public InsertPresentation() { 
          InsertPage = new Page(); 
          ValidationInfo = new PageValidationInfo(); 
        }
        public PageValidationInfo ValidationInfo { get; set; }
        public Page InsertPage { get; set; }
    }
