MVVM: Mediator, Messenger

Question

I've recently downloaded the MVVMExtraLite and there is a helper called Mediator. I've heard of Messenger (in MVVM Light). Are there any differences?

Answer 1

They use the same pattern, Mediator. The Mediator in MVVMXL is more lightweight than Messenger in MVVML, the latter of which provides more types of messages and with generic.
