"After" and "Before" prefixes or suffixes should not be used to indicate pre and post events. The concepts of before and after should be given to
events using the present and past tense.
Noncompliant code example
Class Foo
Event BeforeClose() ' Noncompliant
Event AfterClose() ' Noncompliant
End Class
Compliant solution
Class Foo
Event Closing() ' Compliant
Event Closed() ' Compliant
End Class
