 Inversion of Control is a common pattern that can be used to increase modularity in the codebase of an application when using the MVVM pattern. A frequently used way to enable this is to use _dependency injection_ (DI), which consists of creating a number of services that are injected into backend classes (i.e. passed as parameters to the viewmodel constructors). Doing this allows code using these services not to rely on the implementation details of these services, and it also makes it easy to swap the concrete implementations of these services. This pattern also makes it easy to make platform-specific features available to backend code, by abstracting them through a service which is then injected where needed. Since services are then isolated from where they are used, they become more testable as well.
 
-The MVVM Toolkit doesn't provide built-in APIs to facilitate the usage of this pattern, as dedicated libraries specifically exist for this, such as the `Microsoft.Extensions.DependencyInjection` package. It provides a fully featured and powerful set of dependency injection APIs already and can be easily setup to use the `IServiceProvider` interface. The following guide will refer to this library and provide a series of examples of how to integrate it into applications using the MVVM pattern with the MVVM Toolkit.
