Color Picker for Metro Style app?

Question

I am trying to add ColorPicker to my metro style app. After making a little research, I have found that Extended WPF Toolkit contains ColorPicker. But when I try to add the .dll file to my project via "Add Reference" it says:

"The project targets .NETCore while the file reference targets .NETFramework. This is not a supported scenario."

My question is, How to add this .dll file? Is it possible to compile this .dll so that is targets .NETCore? And Is there any other(simple) way to implement a Color Picker in Metro Style App?

(I am completely new with the concepts of WPF. Please correct me if I made any mistake. )

Answer 1

It's not from Microsoft, and ColorPicker is not yet done (it's described as "in development"), but you can certainly try it. http://winrtxamltoolkit.codeplex.com/

Answer 2

I have recently tested it it works Good in metro apps as well . if your is not working well try to add wpf extended file through Nuget Packages it will work fine :)
