Hi,
The above exception is thrown when running from VS 2010 using the MVVM pattern to set the visibility of a tile.
Running the published app does not throw any exception at all.
Hope someone can help me.
TIA
Ingo
Hi Ingo,Try to set DataContext directly on tiles .<ig:TilePane x:Name="Pane1" Header="Pane1" DataContext="{StaticResource Main}" Visibility="{Binding ShowTile, Converter={StaticResource BoolToVisibilityConverter}}" />
Regards,Marin

Hi Petar,
I appologize for the late response, but I am on Holiday at the moment. Anyway, the suggested answer solves the problem.
Thx,
I'm having exactly this same problem, but I'm not setting DataContext at all (it's inherited).
If I remove the binding on Visiblity it goes away, here's a partial stack:
