How to bind selecteditem of wpf combobox with my.setting?

Question

I'm retriving the serialports and populate a combobox as this:

XAML

<ComboBox Grid.Row="7" Grid.Column="2"     IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding ComPorts, Mode = TwoWay,UpdateSourceTrigger=PropertyChanged}"  SelectedValue="{Binding Path= myserialportx, Mode = TwoWay,UpdateSourceTrigger=PropertyChanged}" SelectedValuePath="myserialportx"/>

VM

Private _comports As String()
    Public Property ComPorts() As String()
        Get
            Return System.IO.Ports.SerialPort.GetPortNames()
        End Get
        Set(ByVal value As String())
            _comports = System.IO.Ports.SerialPort.GetPortNames()
            SetAndNotify(_comports, value)

        End Set
    End Property

Private _myserialportx As String
Public Property myserialportx As String
        Get

            Return _myserialportx
        End Get
        Set(ByVal value As String)
            My.Settings.comport = value
            SetAndNotify(_myserialportx, value)
        End Set
    End Property

I need to save the selected port in my.setting so user does not need to set it anytime, and then I would like to also "preselect" it as it can see what port is actually selected. Any advice?

I figured it out. Seem that when in debug VS save setting in a file that is not the same you see in the editor, switching to release mode it actually work.
