List of .NET Dependency Injection Containers (IOC)

I'm trying to expand my mind around dependency injection in .NET (beyond the two frameworks I've personally used) and an starting to put together a list of .NET Dependency Injection Containers and IOC resources.

Here's what I've got so far. What am I missing?
