An Atypical ASP.NET Core 5 Design Patterns Guide

By: Carl-Hugo Marcotte

Overview of this book

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.

An overview of the Options pattern

In ASP.NET 5, we can use predefined mechanisms to enhance the usage of application settings. These allow us to divide our configuration into multiple smaller objects, configure them during multiple stages of the startup flow, validate them, and even watch for runtime changes with minimal effort.

The Options pattern's goal is to use settings at runtime, allowing changes to the application to happen without changes being made to the code. The settings could be as simple as a string, a bool, a database connection string, or a complex object that holds an entire subsystem's configuration.

This section explores different tools offered by ASP.NET Core to manage, inject, and load configurations and options into our programs. We will tackle different scenarios, from common ones to more advanced ones.

Getting started

The Options pattern in ASP.NET Core 5 allows us to load settings from multiple sources seamlessly. We can customize these...
