Twelve Days of .NET: Day 2: Dependency Injection / IoC

This post is part of my 12 Days of .NET series. This is a (not terribly ambitious) series of posts on .NET topics that came up while I was working on a recent C# Web API project.

One of the first things I wanted to figure out on this project was how to make use of Dependency Injection / Inversion of Control. I’d read about it before, but never really quite figured it out. The original source for the DI/IoC concept is from a Martin Fowler blog post from 2004.

I evaluated a few options for my project, and settled on using Autofac, which is a well-documented IoC container that works well with Web API. This video from Channel 9 helped me figure out how to get started with Autofac and DI in general.

I also considered Ninject and StructureMap. I don’t have much to say about those, since I didn’t wind up using them.

The end result of all this is that I think I finally have a decent working understanding of DI/IoC.
