Injecting an application service into a view model using dependency injection

Dependency injection (DI) is a form of the inversion of control (IoC) pattern. The core idea of DI is that classes don’t create the objects they rely on. Instead, a DI framework resolves the objects centrally and injects them into dependent classes. This technique allows you to easily manage dependencies and achieve loosely coupled architecture, share more code, and create unit tests for separate modules.

In this recipe, we will use DI to inject a data service into a view model:
