MEF

Hi,

I want first to thank @Graeme_Grant for his great suppport in this article
https://www.codeproject.com/Questions/1250791/Load-usercontrol-by-reflection

I copied the code, added the reference and everything is working well !
I have an additional question. I want to have access to the selected listBox item (IView) to call a function inside.

What I have tried:

In MainView.xaml

<ListBox Grid.Row="1" Margin="10" Height="100" 
                 Name="PluginList"
                 ItemsSource="{Binding Plugins}" 
                 ItemTemplate="{StaticResource DetailsTemplate}"
                 SelectionChanged="ListBox_SelectionChanged"/>

in MainWindow.xaml.cs

private void ListBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            IUIViewProviderBase selectedPlugin = PluginList.SelectedItem as IUIViewProviderBase;
            ExportFactory<IView> Iviews = selectedPlugin.Entry;
            IView item = Iviews.CreateExport().Value as IView;
            
        }

The problem is in the last line, CreateExport is creating a new instance of Iview...I don't reach the existing instance.
