As far as I know, none of these are from Microsoft. You would have to purchase them separately.

Perl is from ActiveState: http://www.activestate.com/Products/Visual_Studio_Plug-ins/?_x=1
Cobol is from Fujitsu

There are some other languages for free from Microsoft Research (Asml, F#): http://research.microsoft.com/downloads/


>The cover of the Sep/Oct 2002 CoDe magazine has an image of a hand (mutant, or possibly genetically-modified) with "Visual Studio.Net Languages" inscribed on the palm and the 5 fingers plus a thumb each sporting the name of a different language.
>
>Included in the language names are: Eiffel, Python, Perl and Cobol.
>Does Visual Studio.Net include these languages in the product?

>(I went to a MS site for a product overview and didn't see them listed, but my web acuity is nil so I could have missed them.)
