Synopsis

Apply design patterns to solve problems in software architecture and programming using C# 7.x and .NET Core 2

Key Features

• Enhance your programming skills by implementing efficient design patterns for C# and .NET
• Explore design patterns for functional and reactive programming to build robust and scalable applications
• Discover how to work effectively with microservice and serverless architectures

Book Description

Design patterns are essentially reusable solutions to common programming problems. When used correctly, they meet crucial software requirements with ease and reduce costs. This book will uncover effective ways to use design patterns and demonstrate their implementation with executable code specific to both C# and .NET Core.

Hands-On Design Patterns with C# and .NET Core begins with an overview of object-oriented programming (OOP) and SOLID principles. It provides an in-depth explanation of the Gang of Four (GoF) design patterns such as creational, structural, and behavioral. The book then takes you through functional, reactive, and concurrent patterns, helping you write better code with streams, threads, and coroutines. Toward the end of the book, you'll learn about the latest trends in architecture, exploring design patterns for microservices, serverless, and cloud native applications. You'll even understand the considerations that need to be taken into account when choosing between different architectures such as microservices and MVC.

By the end of the book, you will be able to write efficient and clear code and be comfortable working on scalable and maintainable projects of any size.

What you will learn

• Make your code more flexible by applying SOLID principles
• Follow the Test-driven development (TDD) approach in your .NET Core projects
• Get to grips with efficient database migration, data persistence, and testing techniques
• Convert a console application to a web application using the right MVP
• Write asynchronous, multithreaded, and parallel code
• Implement MVVM and work with RxJS and AngularJS to deal with changes in databases
• Explore the features of microservices, serverless programming, and cloud computing

Who this book is for

If you have a basic understanding of C# and the .NET Core framework, this book will help you write code that is easy to reuse and maintain with the help of proven design patterns that you can implement in your code.

Review

When designing good software, engineers naturally gravitate toward solutions that avoid duplication. We are naturally DRY-Don't Repeat Yourself-often without thinking about it! Developers naturally compartmentalize functionality, create reusable methods, and make helpful classes.

However, many software design patterns have been created over the years. These are useful, general, and reusable solutions to problems you'll see every day. There are more and more developers who are self-taught or who didn't go through a classical software engineer or computer science course at university, and everyone should enjoy the benefits of decades of development of these great design patterns.

Gaurav and Jeffrey have assembled the best and most common patterns and applied them to the open source world of .NET Core and C#. You'll start with OOP, classes, and objects and move your way on to inheritance, encapsulation, and polymorphism. They've covered design principles such as DRY, KISS, and SOLID (these will all make sense very soon!) and applied them to classic patterns that will help you make clear, crisp, and rock-solid (pun intended!) software.

This book is filled with real code that clearly illustrates how to apply all this knowledge to your .NET Core and C# software today. You'll learn how to adopt the Builder pattern, Decorator pattern, Factory pattern, Visitor pattern, and Strategy pattern, and so much more.

These techniques will then be applied to a simple app, then to a web application, and then to more complex problems involving concurrency and parallelism! You'll then apply patterns at a more macro level using solution patterns that will help you move your projects to the cloud in a scalable and maintainable way.

I hope you appreciate this book as much as I did. And I hope you enjoy working with .NET Core and have as much fun as we did making it!
