The Coding Humanist

Continuing on from the basics and model binding, and continuing to kinda make it up as I go along, here we will discuss how to hook up action filters with dependency injection using StructureMap and the new dependency injection hooks in ASP.NET MVC 3.

In our last post we setup the basic dependency resolver infrastructure for StructureMap. Our sample code is still hosted up on Github, so go get if you want to take a look at it. The same caveat to the last discussion still applies: since I know of no samples where StructureMap is used for a full implementation of the IoC hooks in ASP.NET MVC 3, I am kinda making it up as I go along. It is certainly working but time will tell how close my implementation ends up to being awesome. Now that this is out of the way, we need to push on because as is we are in little shape than we were in ASP.NET MVC 2 in terms of IoC support. So let’s start with getting dependency injection going for model binders.

I have become a big fan of the principle of dependency inversion over the last couple years. My tool of choice is StructureMap though I use Unity at work. It actually matters little which you use if you choose to use an IoC library. Much more important is your understanding of the principle and using that to make your software better. But this post is not here to discuss the meanings of these terms; its point is simple: How do you hook up StructureMap to ASP.NET MVC 3’s new IoC hooks?
