While writing concurrent/parallel code, handling state is difficult in an imperative program (something that you would have seen by now). Modern languages and platforms borrow idioms and practices that enable better state management and facilitate strong concurrency models from the functional programming community. In this chapter, we will see what those are and try to understand, through code samples, how to best leverage some of those features (striving for coverage would stretch this chapter to an entire book) to our advantage. We would also see how C# has evolved as a language to bring the best of both worlds (imperative and functional), and to help you apply functional thinking to model real-world scenarios. This chapter will also cover Language Integrated Query (LINQ) as a mechanism for writing compositional code. Through this journey, we will uncover some good design practices, leveraging the functional constructs...

Overview of this book
Knowing about design patterns enables developers to improve their code base, promoting code reuse and making their design more robust.
This book focuses on the practical aspects of programming in .NET. You will learn about some of the relevant design patterns (and their application) that are most widely used. We start with classic object-oriented programming (OOP) techniques, evaluate parallel programming and concurrency models, enhance implementations by mixing OOP and functional programming, and finally to the reactive programming model where functional programming and OOP are used in synergy to write better code.
Throughout this book, we’ll show you how to deal with architecture/design techniques, GoF patterns, relevant patterns from other catalogs, functional programming, and reactive programming techniques.
After reading this book, you will be able to convincingly leverage these design patterns (factory pattern, builder pattern, prototype pattern, adapter pattern, facade pattern, decorator pattern, observer pattern and so on) for your programs. You will also be able to write fluid functional code in .NET that would leverage concurrency and parallelism!
