The MVVM Pattern in .NET MAUI

By: Pieter Nijs

Overview of this book

In today's fast-paced world of modern software development, teams need to be efficient, productive, and capable of rapidly adapting to changes to deliver high-quality products, making it crucial for developers to write maintainable and easy-to-test code. The MVVM Pattern in .NET MAUI helps you to thoroughly explore the Model-View-View Model (MVVM) design pattern. The chapters show you how this pattern helps in structuring code to embrace the separation of concerns, allowing for loosely coupled user interface and application logic, which ultimately empowers you to write more robust, maintainable, and testable code. The book also highlights .NET MAUI's capabilities and features, and enables you to delve into the essential components within the framework that facilitate the application of the MVVM pattern. With the help of a sample application, this definitive guide takes a hands-on approach to walk you through both the essential and advanced usages of the MVVM pattern to ensure that you successfully apply the practical aspects of the pattern to your .NET MAUI projects. By the end of this book, you’ll have gained a comprehensive understanding of the MVVM design pattern and its relevance in the context of .NET MAUI, as well as developed the skills needed to successfully apply it in practice.

Messaging

Messaging is a software architectural pattern that facilitates communication between different parts of an application. In the context of .NET MAUI and MVVM architecture, messaging is typically used to send notifications between loosely coupled components, such as between ViewModels, or from a Model to a ViewModel. This decouples the components and promotes a more modular and maintainable code base.

The concept of messaging is especially useful when data needs to be passed or events need to be communicated between parts of your application that do not have a direct relationship. Instead of tightly coupling these parts by having them directly call each other, you can use a messaging system where one part sends a message that any interested part of your application can receive and react to.

This pattern is a form of the Observer pattern, where an object, named the Subject, maintains a list of its dependents, called Observers, and notifies them automatically of any state...
