Description christopher ireland 2016-12-14 10:57:25 EST 
Using this code:

    public MainWindow()
    {
      InitializeComponent();

      MyTChart.CurrentTheme = ThemeType.None;

      MyTChart.Width = 400;
      MyTChart.Height = 300;
      MyTChart.Axes.Left.SetMinMax(0, 10);
      MyTChart.Axes.Bottom.SetMinMax(0, 10);

      series = new Histogram();
      series.FillSampleValues(100);

      MyTChart.Series.Add(series);
    }

    public Histogram series;


    private void Button_Click(object sender, RoutedEventArgs e)
    {
      Steema.TeeChart.WPF.Export.XAMLFormat xaml = MyTChart.Export.Image.XAML;
      MemoryStream ms = new MemoryStream();
      xaml.Save(ms);
      ms.Position = 0;
      object exportedXaml = XamlReader.Load(ms);
    }

works as expected in TeeChartforNET_4.1.2015.03110, but throws an exception in the current version.
