Hands-On Design Patterns with C# and .NET Core

By: Gaurav Aroraa, Jeffrey Chilberto

Overview of this book

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, including 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.

Chapter 10 – Reactive Programming Patterns and Techniques

  1. What is a stream?

A sequence of events is called a stream. A stream can emit three things: a value, an error, and a signal for completion.

  1. What are reactive properties?

Reactive properties are binding properties that react when an event triggers.

  1. What is a reactive system?

On the basis of the Reactive Manifesto, we can conclude that reactive systems are as follows:

    • Responsive: Reactive systems are event-based design systems because of this design approach; these systems are quick to respond to any request in a short time.
    • Scalable: Reactive systems are reactive in nature. These systems can react to change the scalability rate by expanding or reducing the allocated resources.
    • Resilient: A resilient system is one that would not stop, even if there is any failure/exception. Reactive systems are designed in...
