VS C++ 2013 RC - Error: DataVisualization

This is on a fresh install of VS 2013 RC, and I chose .NET 4.5.1 and x64 platform.
The following line generates an error.

System::Windows::Forms::DataVisualization::Charting::Chart ^chart;

The word DataVisualization is underlined with a red squiggly line, and the error code is C3083.  VS C++ 2010 didn't generate an error.
