Hi,

How to avoid the problem below (I see what the problem is : you get two items with the same name) but I can't find any working code for a fix. Simple UserControl:

UserControl x:Class="WpfApplication1.MinimalControl"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Height="300" Width="300">
    <TextBlock x:Name="Fred" />
</UserControl>

Used in this form:

<Window x:Class="WpfApplication1.MinimalForm"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:uc="clr-namespace:WpfApplication1"
    Title="MinimalForm" Height="300" Width="300">
    <StackPanel>
        <Canvas x:Name="ACanvas">
            <uc:MinimalControl />
            <uc:MinimalControl />
        </Canvas>
        <Button Click="Button_Click" >Try</Button>
    </StackPanel>
</Window>

Here's the test code behind:

using System.Windows;
using System.Windows.Controls;

namespace WpfApplication1
{
    /// <summary>
    /// Interaction logic for MinimalForm.xaml
    /// </summary>
    public partial class MinimalForm : Window
    {
        public MinimalForm()
        {
            InitializeComponent();
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            string s = System.Windows.Markup.XamlWriter.Save(ACanvas);
            System.IO.StringReader stringReader = new System.IO.StringReader(s);
            System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create(stringReader);
            //Exception here:
            Canvas x = (Canvas)System.Windows.Markup.XamlReader.Load(xmlReader);
        }
    }
}

Any way of manipulating the NameScope (or something) to avoid this ?
