AutoCompleteBox - WPF Toolkit

I want to use the AutoCompleteBox in my WPF application but i cannot find it in visual studio. I have VS 2010 ultimate. I just downloaded and installed WPFToolkit.msi and ran it. When i open VS i cannot find the control. Where can i find it? Do i have to 开发者_开发知识库reference it somehow? I also have the .dll but i dont know if i need to put that somewhere? Thank you.
