Fortify is reporting NullDereference on line 2 of the following code however the code is clearly checking for null on line 1. How do I resolve this issue?
If Not collectUpdates.IsNullOrEmpty() Then
For Each update As CollectStatusUpdate In collectUpdates
...
Next
End If
<Extension()>
Public Function IsNullOrEmpty(Of T)(source As IEnumerable(Of T)) As Boolean
Return source Is Nothing OrElse Not source.Any()
End Function
