An Atypical ASP.NET Core 5 Design Patterns Guide

A .NET developer’s guide to crafting robust, maintainable, and flexible web apps by leveraging C# 9 and .NET 5 features and component-scale and application-scale design patterns

Key Features

• Apply software design patterns effectively, starting small and progressing to cloud-scale
• Discover modern application architectures such as vertical slice, clean architecture, and event-driven microservices
• Explore ASP.NET design patterns, from options to full-stack web development using Blazor

Book Description

Design patterns are a set of solutions to many of the common problems occurring in software development. Knowledge of these design patterns helps developers and professionals to craft software solutions of any scale.

ASP.NET Core 5 Design Patterns starts by exploring basic design patterns, architectural principles, dependency injection, and other ASP.NET Core mechanisms. You’ll explore the component scale as you discover patterns oriented toward small chunks of the software, and then move to application-scale patterns and techniques to understand higher-level patterns and how to structure the application as a whole. The book covers a range of significant GoF (Gangs of Four) design patterns such as strategy, singleton, decorator, facade, and composite. The chapters are organized based on scale and topics, allowing you to start small and build on a strong base, the same way that you would develop a program. With the help of use cases, the book will show you how to combine design patterns to display alternate usage and help you feel comfortable working with a variety of design patterns. Finally, you’ll advance to the client side to connect the dots and make ASP.NET Core a viable full-stack alternative.

By the end of the book, you’ll be able to mix and match design patterns and have learned how to think about architecture and how it works.

What you will learn

• Apply the SOLID principles for building flexible and maintainable software
• Get to grips with .NET 5 dependency injection
• Work with GoF design patterns such as strategy, decorator, and composite
• Explore the MVC patterns for designing web APIs and web applications using Razor
• Discover layering techniques and tenets of clean architecture
• Become familiar with CQRS and vertical slice architecture as an alternative to layering
• Understand microservices, what they are, and what they are not
• Build ASP.NET UI from server-side to client-side Blazor

Who this book is for

This design patterns book is for intermediate-level software and web developers with some knowledge of .NET who want to write flexible, maintainable, and robust code for building scalable web applications. Knowledge of C# programming and an understanding of web concepts like HTTP is necessary.
