Well both libraries from this site include OBEX server functionality and both also include simple applications. From the 32feet.NET library compile and run the DesktopObexListener sample. You may want to change the path where it writes the files to, other that than it should be ok.

Otherwise see "Brecham ObexServer r2" and its CmdlineRunner application.
