BeforeProperties AfterProperties ListItem in Sharepoint Event Receivers

Important while developing sharepoint event receivers.

BTW, I've read a article that said change Element.xml Synchronization to Synchronous, we can get BeforeProperties on List events, but I cannot find this reference now.

I'll make some test to confirm it. (Maybe many days or months later......)

List:

List	BeforeProperties	AfterProperties	properties.ListItem
ItemAdding	No value	New value	Null
ItemAdded	No value	New value	New value
ItemUpdating	No value	Changed value	Original value
ItemUpdated	No value	Changed value	Changed value
ItemDeleting	No value	No value	Original value
ItemDeleted	No value	No value	Null

Library:

Library	BeforeProperties	AfterProperties	properties.ListItem
ItemAdding	No value	No value	Null
ItemAdded	No value	No value	New value
ItemUpdating	Original value	Changed value	Original value
ItemUpdated	Original value	Changed value	Changed value
ItemDeleting	No value	No value	Original value
ItemDeleted	No value	No value	Null
