Creating a new ``Exception`` without actually throwing it is useless and is probably due to a mistake.

== Noncompliant Code Example

----
If x < 0 Then
    Dim ex = New ArgumentException("x must be nonnegative")
End If
----

== Compliant Solution

----
If x < 0 Then
    Throw New ArgumentException("x must be nonnegative")
End If
----
