Having all branches in a ``Select Case`` or ``If`` chain with the same implementation is an error. Either a copy-paste error was made and something different should be executed, or there shouldn't be a ``Select Case`` / ``If`` chain at all.

== Noncompliant Code Example

----
Dim b As Integer = If(a > 12, 4, 4)

If b = 0 Then
    DoTheThing()
Else
    DoTheThing()
End If

Select Case i
    Case 1
        DoSomething()
    Case 2
        DoSomething()
    Case 3
        DoSomething()
    Case Else
        DoSomething()
End Select
----

== Exceptions

This rule does not apply to ``If`` chains without ``Else``-s, or to ``Select Case``-es without ``Case Else`` clauses.

----
If b = 0 Then ' No issue, this could have been done on purpose to make the code more readable
    DoTheThing()
ElseIf
    DoTheThing()
End If
