hi,

i getting the error as below when i build the project....

Error 1 'System.Windows.Media.CaptureSource' does not contain a definition for 'AsyncCaptureImage' and no extension method 'AsyncCaptureImage' accepting a first argument of type 'System.Windows.Media.CaptureSource' could be found (are you missing a using directive or an assembly reference?) D:\master\SLARToolkit 1.0.2.0\slartoolkit-44719\trunk\SLARToolKit\Source\SLARToolKitBalderSample\MainPage.xaml.cs 172 24 SLARToolKitBalderSample

any solution for this? thanks.

The method is called CaptureImageAsync
