==== Noncompliant code example

[source,vbnet,diff-id=1,diff-type=noncompliant]
----
Class Person
    Private age As Integer

    <Pure> ' Noncompliant: The method makes a state change
    Private Sub ConfigureAge(ByVal age As Integer)
        Me.age = age
    End Sub

    <Pure>
    Private Sub WriteAge() ' Noncompliant
        Console.WriteLine(Me.age)
    End Sub

End Class
----

==== Compliant solution

[source,vbnet,diff-id=1,diff-type=compliant]
----
Class Person
    Private age As Integer

    Private Sub ConfigureAge(ByVal age As Integer)
        Me.age = age
    End Sub
    
    <Pure>
    Private Function Age() As Integer
        Return Me.age
    End Function

    ' or remove Pure attribute from the method

    Private Sub WriteAge()
        Console.WriteLine(Me.age)
    End Sub

End Class
