==== Noncompliant code example

[source,vbnet,diff-id=1,diff-type=noncompliant]
----
Public Class BaseClass
    Public Overridable Sub MyMethod(ByVal Optional i As Integer = 1)
        Console.WriteLine(i)
    End Sub
End Class

Public Class DerivedClass
    Inherits BaseClass

    Public Overrides Sub MyMethod(ByVal Optional i As Integer = 1)
        ' ...
        MyBase.MyMethod() ' Noncompliant: caller's value is ignored
    End Sub

    Private Shared Function Main(ByVal args As String()) As Integer
        Dim dc As DerivedClass = New DerivedClass()
        dc.MyMethod(12) ' prints 1
    End Function
End Class

    End Sub
End Class

Public Class DerivedClass
    Inherits BaseClass

    Public Overrides Sub MyMethod(ByVal Optional i As Integer = 1)
        ' ...
        MyBase.MyMethod(i)
    End Sub

    Private Shared Function Main(ByVal args As String()) As Integer
        Dim dc As DerivedClass = New DerivedClass()
        dc.MyMethod(12) ' prints 12
