S1067 — Expressions should not be too complex

Why is this an issue?

Complex boolean expressions are hard to read and so to maintain.

Noncompliant code example

With the default threshold value of 3

If ((condition1 AndAlso condition2) OrElse (condition3 AndAlso condition4)) AndAlso condition5) Then  'Noncompliant
  ...
End If

Compliant solution

If ((MyFirstCondition() OrElse MySecondCondition()) AndAlso MyLastCondition()) Then
  ...
End If
