Why is this an issue?
Calling the Not operator twice does nothing: the second invocation undoes the first. Either this is a bug, if the operator was
actually meant to be called once, or misleading if done on purpose.
Noncompliant code example
Dim b As Boolean = False
Dim c As Boolean = Not Not b 'Noncompliant
Compliant solution
Dim b As Boolean = False
Dim c As Boolean = b 'Compliant
