Event Aggregation with MEF (with and without EventAggregator)

The title probably sounds like an oxymoron, but it is not. Recently there was a question on our CodePlex forums from Denis Vuyka about whether or not MEF supports anything like EventBroker for pub/sub type communication. Asking such a question makes a lot of sense, as if you are building open-ended systems of extensions, you…

Composite Application Guidance - What is it?
