I would like to add a toolbar, that looks like the one in the Windows 7 Explorer (see picture below), to a WPF-application. Because I'm new to WPF I wondered if there is a WPF-Control (free / open source) I can use instead of having to create a new one.
I already searched for it but could not find anything useful.
