This book is about OOP in C# and is a continuation of the previous book, and the current book assumes a knowledge of OOP corresponding to the content of C# 3. The book deals with the implementation of strings in C# and else describes generic types and in relation to that, collection classes, but also concepts as delegates, lambda expressions and operator overriding.
