C# - wpf - Cannot add ContextMenu to ListView since Framework Downgrade

I got the following code in my xaml file:

...
<ListView ...>
    <ListView.ItemContainerStyle>
        <Setter Property="ContextMenu">
            <Setter.Value>
                <ContextMenu>
                    ...
...

If I run the application in debug mode I get a System.Windows.Markup.XamlParseException at the ContextMenu with an additional information as follows:

German original:

Additional information: Einem Objekt vom Typ "System.Object" kann kein Inhalt vom Typ "System.Windows.Controls.ContextMenu" hinzugefügt werden.

My english translation (I dont know the original english message):

Additional information: You cannot add content of the type "System.Windows.Controls.ContextMenu" to an object of the type "System.Object".

I ported the application from .NET4.0 down to .NET3.5 for compatibility reasons. In .NET4.0 it worked without problems.

What's the problem and how to solve this?

    <MenuItem Name="mnuEdit" Header="_Edit" Click="MenuItem_Click" />
</ContextMenu>
<Style TargetType="ListBoxItem">
    <Setter Property="ContextMenu" Value="{DynamicResource contextMenu}" />
