MVVM with Prism 101 – Part 5b: ServiceLocator vs Dependency Injection

Now that Mark J. Miller showed the View-Model in Part 5, it;s time to see how to wire up the View-Model to the View.

First, let me define a few things. First, Inversion of Control is a pattern wherein creation of objects is delegated in an effort to simplify instantiation and/or defer it until runtime. Huh? Inversion of Control is a means of programming against interfaces. Your classes reference interfaces at design-time and then delegate the creation of the concrete classes to a single component or service. The result is you now have a only a single dependency – the “Container” – instead of a complex hierarchy of dependencies.
