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.

Goal

The role of the Operation Result pattern is to give an operation (a method) the possibility to return a complex result (an object), which allows the consumer to:

  • [Mandatory] Access the success indicator of the operation (that is, whether the operation succeeded or not).
  • [Optional] Access the result of the operation, in case there is one (the return value of the method).
  • [Optional] Access the cause of the failure, in case the operation was not successful (error messages).
  • [Optional] Access other information that documents the operation's result. This could be as simple as a list of messages or as complex as multiple properties.

This can go even further, such as returning the severity of a failure or adding any other relevant information for the specific use case. The success indicator could be binary (true or false), or there could be more than two states, such as success, partial success, and failure. Your imagination (and your needs) is your limit...
