I have a class Application that I need to override with INotifyPropertyChanged events. I have written the logic to override the original class and ended up creating SuperApplication

I am pulling the data from a library though, and cannot change the loading logic. I just need a way to get the data from the original class into my superClass. I've tried things like superClass = (SuperApplication)standardClass; but it hasn't worked.

How would I go about doing this?

If it helps, this is the code I'm using to override the original class:

public class SuperCreditApplication : CreditApplication
{
    public SuperCreditApplicant Applicant { get; set; }
    public SuperCreditApplicant CoApplicant { get; set; }
}

public class SuperCreditApplicant : CreditApplicant
{
    public SuperProspect Prospect { get; set; }
}

public class SuperProspect : Prospect, INotifyPropertyChanged
{
    public State DriverLicenseState
    {
        get
        {
            return DriverLicenseState;
        }
        set
        {
            DriverLicenseState = value;
            OnPropertyChanged("DriverLicenseState");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    private void OnPropertyChanged(string propertyName)
    {
        if (PropertyChanged != null)
        {
            PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}
