Hi,

I'm trying to simply have my chart's legend items wrap their text, rather than being cuttoff.

Pretty basic thing really. I was surprised to hear how complicated it was to do this. I followed the instructions at http://www.telerik.com/help/silverlight/radchart-styling-and-appearance-styling-chart-legend.html, but I'm getting an error before I even change anything. As soon as I set the LegendItemStyle in the ChartLegendStyle via a setter, Visual Studio underlines the whole line in blue squigly, and holding the mouse over the squigly yields the error message: "Catastrophic Failure (Exception from HRESULT: 0x8000FFFF (E_UNEXPECTED)).

Here is my code. I chose to edit the style in a copy, stored in App.xaml.

<Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
