Exploring MVVM and Data Binding
In the previous chapter, we explored how to construct user interfaces (UIs) using XAML. In this chapter, we will dive into the Model-View-View-Model (MVVM) pattern and data binding. The MVVM pattern, a widely adopted architectural pattern, is key in creating maintainable, scalable, and testable applications. In the context of .NET MAUI, MVVM separates the user interface logic, data, and the app’s structure into three distinct components: Model, View, and ViewModel. This separation leads to a clean and organized codebase, making it easier to develop and maintain the application. Data binding is a technique that connects the view (UI) with the ViewModel in a way that the UI reflects the ViewModel’s data and changes synchronously and automatically.
In this chapter, our initial focus will be on introducing MVVM and data binding. For a better design and cleaner code, we will employ the MVVM Toolkit, part of the .NET Community Toolkit. The...
