I doubt that. If I am not completely wrong, .net uses bytecode (like Java)
aka. CIL (Common Intermediary Language).
(http://www.msdnaa.net/Resources/Display.aspx?ResID=373 )

I would not know how you can combine cil code with obj. files. If somebody
knows more I would love to read about it. It is one of the (many) reasons I
don't -and have advised others- to jump on the .net bandwagon. I know for
sure that the Javascript (in M$ language Jscript) development part of VS7
can not be used for developing real ecmascript applications.

with kind regards
