Javascript autocompletion plugin for VS. Net

I'm doing a lot of work in Javascript with Visual Studio .Net 2008. It would be nice to have some sort of plugin to do auto completion for Javascript (a bit like ctrl space and a list开发者_运维百科 of options come up in Java/C# etc).

Is there such plugin/tool out there?

Thanks.

Yes.

Visual Studio 2008 Service Pack 1

I haven't tried it, but the VS2010 beta has even better Javascript Intellisense.
