WPF: after add WPF Toolkit DLL

Question

After add rrr DLL i am looking at this tutorial. Do i need to add some reference in my XAML in order to find chartingToolkit:Chart ?

Answer 1

At the end of the opening Window tag, the tutorial's code imports the namespace your are talking about. Do you have the following XAML in your opening Window tag?

xmlns:chartingToolkit= "clr-namespace:System.Windows.Controls.DataVisualization.Charting; assembly=System.Windows.Controls.DataVisualization.Toolkit"

If you are unfamiliar with referencing CLR namespaces from XAML, I strongly recommend reading this MSDN introduction on the topic.
