Lightweight IoC container that works in Unity3D

We rolled our own based on ideas from Sebastiano Mandalà, which you can find here: https://github.com/modesttree/Zenject

I know this thread is old, but if anyone comes along who's interested in an IoC solution for Unity3D, this open source project went live today: http://thirdmotion.github.io/strangeioc/

Eventually I did not find any working implementation of an IoC container made specifically for unity3D framework (http://unity3d.com/), so I decided to implement one on my own and I blogged about it here: http://blog.sebaslab.com/ioc-container-for-unity3d-part-1/
