C# Fundamentals for Absolute Beginners: (17) Working with Classes and Inheritances in the .NET Framework Class LibraryAug 12, 2014 at 1:48 PM
@arifuddin: I've not read that book, so I can't comment. The focus of this lesson is to explain how Microsoft uses classes ... how one class inherits from another class. They build a class that has basic functionality, then create other classes with more specialized / advanced functionality based on the original. If you can understand that basic idea, you've gotten enough out of this lesson. Don't worry about creating inheritance hierarchies in your applications ... that would require a bit more time and explanation as to why and how you do that.
