I was wondering how to do this, consider the following classes

public class Fruit
{
    public string Name { get; set; }
    public Color Color { get; set; }
}
public class Apple : Fruit
{
    public Apple()
    {

    }
}

How can I instantiate a new fruit but upcast to Apple, is there a way to instantiate a bunch of Fruit and make them apples with the name & color set. Do I need to manually deep copy?

Of course this fails

Fruit a = new Fruit();
a.Name = "FirstApple";
a.Color = Color.Red;
Apple wa = a as Apple;
System.Diagnostics.Debug.Print("Apple name: " + wa.Name);

Do I need to pass in a Fruit to the AppleCTor and manually set the name and color( or 1-n properties) Is there an better design to do this?
