Error loading designer for ListPage.xaml

Jan 7, 2011 at 7:45 PM

I am getting the following error when  reviewing the ListPage.xaml ...

Layout measurement override of element 'Microsoft.Windows.Design.Platform.SilverlightViewProducer+SilverlightContentHost' should not return PositiveInfinity as its DesiredSize, even if Infinity is passed in as available size.

Amyone have an idea what the problem is?
