Dependency Injection with .NET MAUI Explained! Full Beginner's Guide

.NET MAUI supports the dependency injection (DI) software design pattern, which is a technique for achieving Inversion of Control (IoC) between classes and their dependencies. On top of that it fully supports constructor injection and full dependency resolution when navigating when using Shell. I break down every little thing you need to know about DI, IoC, and constructor injection with .NET MAUI. Note: That [ICommand] is now [RelayCommand] from the .NET community toolkit!
