I am new to visual studio 2008 and WPF programming. I have searched high and low but cannot seem to find much information about adding a file explorer window into my WPF application. The little bit of information I have found only details commercially licensed plugins.

Am I overlooking something or is there no control I can add in from the tool box? I am simply wanting to add in a control where I can graphically browse a directory tree and select a file for manipulation.
