Summary

In this chapter, we delved into two pivotal topics in the architecture of modern applications: DI and messaging. First, we explored DI, a technique for achieving loose coupling between objects and their dependencies. In the context of the MVVM pattern, we utilized this technique to inject services and other dependencies into our ViewModels, enhancing their testability and maintainability.

The latter part of this chapter focused on messaging, another integral component in MVVM applications for promoting decoupled communication between components. We examined WeakReferenceMessenger provided by the MVVM Toolkit, which facilitates loose coupling in the application.

In essence, this chapter aimed to reinforce the importance of loose coupling in software design, showcasing how both DI and messaging contribute significantly to the creation of maintainable and testable applications.

In the upcoming chapter, we’ll delve deep into the intricacies of navigation in .NET...
