Build errors when downloaded source code

Mar 10, 2015 at 7:16 PM
I'm getting build errors when I downloaded the source code and tried to run it.

Undefined CLR namespace. The 'clr-namespace' URI refers to a namespace 'System.Windows.Controls.WpfPropertyGrid' that is not included in the assembly. C:\Users\rdoshi\Downloads\wpfpropertygrid-76924\WpfPropertyGrid\Main\WpfPropertyGrid\Themes\PropertyGrid.xaml 4 15 WpfPropertyGrid

Can someone please help ?
