This book focuses on real-world, easy-to-understand examples of code in a one-on-one style. Refactoring examples are performed and reasons why this refactoring should be applied are detailed. The book is structured from less advanced topics to more advanced topics; but is designed so that reading from beginning to end is not necessary. This book is primarily for developers who want to refactor their code in Visual Studio. However, the book can be used by anyone using Visual Studio. Developers, designers, and architects who are eager to improve the performance of their craft will find this book useful because it details refactoring existing code to use recognized and established patterns and principles to improve code structure and architectural behavior. The book assumes that the reader knows both Visual Studio and C#, but no previous knowledge of refactoring is required.
