        Get
            Return GetValue(SquareColorProperty)
        End Get

        Set(ByVal value As Brush)
            SetValue(SquareColorProperty, value)
        End Set
    End Property

    Public Shared ReadOnly SquareColorProperty As DependencyProperty = _
                           DependencyProperty.Register("SquareColor", _
                           GetType(Brush), GetType(CircleInSquare), _
                           New FrameworkPropertyMetadata(Brushes.Gray))

End Class
