Brady, loving the posts! You're doing a great job.
I recall listening to a podcast a few years ago that had Glenn Block stating MEF was not trying to replace other IoC containers. I actually wrote it off as something that was cool but generally overkill for the small scale projects that I do. I think the podcast was Herding Code and do realize it was a few years ago and things change fast.
It seems even simpler than Ninject, which I've been using based on it's own simplicity, but is MEF not overkill for simple internal decoupling?
Is it just as simple for MEF to do injection patterns other than constructor injection? Specifically property setter injection?
