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.

What are microservices?

Besides being a buzzword, microservices represent an application that is divided into multiple smaller applications. Each application, or microservice, interacts with the others to create a scalable system.

Here are a few principles to keep in mind when building microservices:

  • Each microservice should be a cohesive unit of business.
  • Each microservice should own its data.
  • Each microservice should be independent of the others.

Furthermore, everything we have studied so far – that is, the other principles of designing software – apply to microservices but on another scale. For example, you don't want tight coupling between microservices (solved by microservices independence), but the coupling is inevitable (as with any code). There are numerous ways to solve this problem, such as the Publish-Subscribe pattern.

There are no hard rules about how to design microservices, how to divide them, how big they should be, and...
