Remarks
The SPListEventReceiver class is not instantiated, but the list event receiver class of a custom event handler must derive from this class and override its methods for the event types that are handled.
The SPListEventReceiver class notifies registered entities of list schema events, supporting list schema operations and the addition or removal of content types.
Like other events, list events come in both Before synchronous and After asynchronous variants. In addition, like other events, list events will generally not occur as the result of a bulk operation. For example, creating a new Windows SharePoint Services list inherently creates a set of fields, but FieldAdding events do not occur.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
