[IronPython] Silverlight DataBinding Not Working

Hi,

   I am trying out some sample Silverlight code with IronPython and I found
that the data binding does not work properly.
The app.xaml is as below:

<UserControl x:Class="System.Windows.Controls.UserControl"
 xmlns="http://schemas.microsoft.com/client/2007"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <Grid x:Name="layout_root" Background="White">
    <StackPanel>
        <Slider x:Name="sliderFontSize" Margin="3" Minimum="1" Maximum="40"
Value="10" />
        <TextBlock x:Name="lblMessage" Text="Hello World" Margin="5"
FontSize="{Binding ElementName=sliderFontSize,
Path=Value,Mode=TwoWay}"></TextBlock>
        <Button x:Name="cmdClickMe" Content="Click Me!" Margin="5"></Button>
    </StackPanel>
  </Grid>
</UserControl>
This XAML when used in a C# Silverlight app reflects the correct data
binding behaviour but does not work when used with IronPython and Chiron.
Mainly the font size of the text block is not updated.
Does anyone have any idea about this?

Thanks,
Shyam
