To create the event handler 1. Start Microsoft Visual Studio 2010. 2. On the File menu, point to New, and then click Project. 3. In Project Types, under Visual Basic or C#, select Event Receiver. ...
So wait, is there a difference between an event receiver and an event handler? Or is it just that what is commonly referred to as an event handler in most environments is for some reason called an event receiver in SharePoint?
For example in this link - http://blog.sharedove.com/adisjugo/index.php/2009/03/12/develop-and-deploy-a-sharepoint-event-receiver-from-the-scratch/ - the author uses "event handler" throughout, except when referencing the SharePoint class names. Googling for "event receiver" turns up mostly SharePoint references, with a few Microsoft Office hits here and there.
If anyone has the definitive word on this, I'd appreciate it.
