# What's IoC good for, Really?

By Roy Osherove October 25, 2007 In [.NET](https://osherove.com/blog/category/net), [.Net 2.0](https://osherove.com/blog/category/net-2-0), [Architecture](https://osherove.com/blog/category/architecture), [altnet](https://osherove.com/blog/category/altnet), [altnetconf](https://osherove.com/blog/category/altnetconf)

**Historical article** · Originally published October 25, 2007; technical details may be outdated.

Oren has one of the best one liners about the benefits of [Inversion Of Control](http://martinfowler.com/articles/injection.html) Containers in a project [in this post](http://www.ayende.com/Blog/archive/2007/10/20/Dependency-Injection-doesnt-cut-it-anymore.aspx):

"Other people on my team keep adding components, and they aren't even aware that they have IoC there. **They just know that if they put the IFooService in the ctor, they will get it when the code is running**. And if they add IBarService and BarServiceImpl, they will be available to any component that uses them."

[Here's a quick "Getting Started"](http://castleproject.org/container/gettingstarted/part1/index.html) if you've never seen this before, using the Castle Windsor Container Framework for .NET.
