Almost every web developer knows about FireBug console window, but I still see some developers who uses javascript alert command for tracing javascript output. You can actually write to FireBug console window using console command from your javascript. However since this is not a standard javascript command, Visual Studio doesn't have itellisence for it. So, here is vsdoc file, which enables intellisence for console command.

P.S.
Thanks to David Murdoch for creating it.
