This programming language model is used sparingly in VB 6 but is one of the cornerstones of VB.NET. Knowing the ins and outs of it will make an application migration project easier and also prepare you for additional work in VB.NET. What is the model?

VB6 was primarily a procedural language with limited OOP support. VB.NET is built entirely on object-oriented programming (classes, inheritance, polymorphism, encapsulation). Understanding OOP is essential for VB.NET development and makes migration easier - you'll recognize which patterns to preserve and which need redesign.
