The name "ColorPicker" does not exist in the namespace "clr-namespace:Xceed.Wpf.Toolkit"

I'm completely new to WPF and need help accessing the WPF toolkit.

I wanted to use the color picker in my app (on VS2015 with SDK installed on framework 4.6.1). I installed the WPF toolkit 2.9 with Nuget - no problems. I can access the color picker from the binary dll in my app - also no problems.

I then downloaded the source code and themes. The source code compiled OK, but the XAML code for the theme I'm using (general) can't find the color picker, color canvas etc. The debug errors says

The name "ColorPicker" does not exist in the namespace "clr-namespace:Xceed.Wpf.Toolkit"

Obviously it does exist there otherwise I wouldn't have been able to access it in the binary and it shows up the object browser. The same errors occur with the Aero theme.

Why can't I access the toolkit objects from the XAML markup ?
