Hey I wonder if someone could help me. I try to bind my imported test modules to my view, see below for code:

<UserControl x:Class="AvanadeTT.Controls.Views.Module"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:ignore="http://www.ignore.com"
    xmlns:local="clr-namespace:InterfaceLibrary;assembly=InterfaceLibrary"
    mc:Ignorable="d ignore"
    Height="600" Width="600">
     <Grid>
      <TreeView Name="ModuleTV">
        <TreeView.Resources>
            <HierarchicalDataTemplate  DataType="{x:Type local:ITestTest}"        ItemsSource="{Binding Modules}" >
                <TextBlock Text="{Binding Name}"/>
            </HierarchicalDataTemplate>
            <HierarchicalDataTemplate  DataType="{x:Type local:ITestTest}" ItemsSource="{Binding Author}" >
                <TextBlock Text="{Binding Name}"/>
            </HierarchicalDataTemplate>
        </TreeView.Resources>
    </TreeView>
        <Button Content="OK" HorizontalAlignment="Left" Margin="488,534,0,0"     VerticalAlignment="Top" Width="94" Height="31"/>
    </Grid>
</UserControl>

Now my viewmodel does get the data so that is not what the problem is. The editor gives the following stacktrace and error:

'Set property 'System.Windows.ResourceDictionary.DeferrableContent' threw an exception.' Line number '13' and line position '14'.

The fusionlog shows this content:

Good to know maybe is that my Interface definition is a shared assembly, this because I import via the MEF framework.

My InterfaceLibrary is being copied to my debug folder and this also shows there.

Try to strong name the assembly and add it to the GAC. – Verbenaceous
The assembly is strongly named, it's added to the GAC dynamicly. So that isn't the problem. Thanks for your responding – Inga

The error says that your problem is line 13. I would be surprised if your ItemsSource binding was the problem. I would guess that there's some sort of problem finding the ITestTest type. I couldn't tell you why.
