After an introduction to abstract data types and their initial implementation using structures, Michael McMillan analyzes standard OOP topics, including class design, inheritance, access modifiers and scoping issues, abstract classes, design and implementation of interfaces and design patterns, and refactoring in VB.NET. More advanced OOP topics are covered as well (reflection, object persistence, and serialization.) Finally, he demonstrates OOP techniques for standard Windows applications; for database applications using ADO.NET; for Web-based applications using ASP.NET; and for Windows service applications.
