Lesson 15 - Type casting and object hierarchy in VB.NET
In the previous lesson, Interfaces in VB.NET, we learned about interfaces and created a Pterodactyl class in Visual Basic .NET. In today's tutorial, we'll continue working on our interface project. We will also go over type casting and reveal more secrets of the object-oriented programming.
Let's go back to our previous project and change the code in the Main() method to have our pterodactyl stored in a variable of the IBird type:
Dim bird As IBird = New Pterodactyl()
