Implement design patterns in .NET Core 3 using the latest versions of the C# and F♯ languages. This book provides a comprehensive overview of the field of design patterns as they are used in today's developer toolbox. This new edition introduces topics such as Functional Builder, Asynchronous Factory Method, Generic Value Adapter, and new Composite Proxies, including one that attempts to solve the SoA/AoS problem. Using the C# and F♯ programming languages, Design Patterns in .NET Core 3 explores the classic design pattern implementations and discusses the applicability and relevance of specific language features for implementing patterns. You will learn by example, reviewing scenarios where marks are applicable. MVP and patterns expert Dmitri Nesteruk demonstrates possible implementations of patterns, discusses alternatives and pattern inter-relationships, and illustrates how a dedicated refactoring tool (ReSharper) can be used to implement design patterns easily. What You Will Learn Become familiar with the latest pattern implementations in C# 8 and F♯ 5. Know how to better reason about software architecture, Understand the process of refactoring code to patterns, and Refer to research. Proven variations of patterns, Study complete, self-contained examples, including many that advanced cover scenarios, and Use the latest implementations of C# and Visual Studio/Rider/ReSharper. This book is for developers who have some experience in the C# language and want to expand their comprehension of the art of programming by leveraging design approaches to solving modern problems.
