Object-oriented programming in VB.NET
Lesson 1 - Introduction to object-oriented programming in VB.NET
In this tutorial, we'll introduce object-oriented programming, explain it's historical origins as well as terms such as classes, attributes, and methods.
Lesson 2 - First object-oriented application in VB - Hello object world
In this tutorial we'll create our first object-oriented app in VB.NET - Hello object world. We'll create classes, fields and parametrized methods.

Lesson 5 - Warrior for the arena in VB.NET
In this Visual Basic .NET tutorial, we'll create a warrior object (class). Its instances will battle in the arena next time.
Lesson 6 - Arena with warriors in VB.NET
In this tutorial, we'll finish our arena with warriors. As a result, we'll have an object-oriented application simulating a board game.
Lesson 7 - Inheritance and polymorphism in VB.NET
In this tutorial, we'll go over object inheritance and polymorphism. We'll learn how to reuse code and explain what the protected access modifier is.
Lesson 8 - Arena with a mage in VB.NET (inheritance and polymorphism)
In this VB.NET lesson, you'll learn how to call base constructors, override methods and put what you know about inheritance and polymorphism to the test.

Lesson 14 - Interfaces in VB.NET
In this tutorial you'll learn about interfaces in Visual Basic, auto-implement them with Visual Studio, and how to replace multiple inheritances with them.
Lesson 15 - Type casting and object hierarchy in VB.NET
You'll learn how to cast an instance to another data type using interfaces in Visual Basic .NET. You will also learn about and create an object hierarchy.
Lesson 16 - Abstract class, comparing and operator overloading in VB.NET
This tutorial explains abstract classes in Visual Basic. We'll learn about interfaces, implement custom comparing with IComparable, and overload operators.
