This is one of the most helpful software engineering books I've ever read. It is most useful for people who have some real world experience in .NET development.
This book discusses how to decompose complex software systems into modules that can be implemented relatively independently. The discussion first begins with fundamental problem in software design, managing complexity.
There is a minimum expectation that, if you are a software developer, irrespective of programming language or discipline that you have actually read this book, at least more than twice! This book should be compulsory reading for anyone, working with code in any capacity.
Clean code and the practices are about eliminating or at least attempting to reduce complexity. Although clean code solutions may seem elegant and efficient, they are not always easy and are often the direct result of combating complexity!
