I am a newbie to Windows Phone 8 app programming in C# and I am trying to create an array of textboxes. I have the array being created and being added as children of a Stack Panel, and I am trying to get it to display more than a few textboxes, and I read that it can be done if the CanContentScroll property is set to 'true' as it is set to 'false' by default. However, when I try to add it, it is not recognised by intellisense. Can you help me?

```
<ScrollViewer VerticalScrollBarVisibility="Auto" CanContentScroll="True" Margin="10,135,10,7" >
            <StackPanel x:Name="TextBoxStack" HorizontalAlignment="Left" Height="419" Margin="0,166,0,0" VerticalAlignment="Top" Width="446"/>
</ScrollViewer>

```

I am using VS2013, and the System.Phone.Controls and System.Windows.Controls modules are included correctly.
