How to make a "Link" REFERENCE to a project (no DLL, no file copy)

[pamelafluente]

Hi,

Assume that I have a web application.
I want to be able to use the classes that are
in another project (say a Win application)
on which I am working at the same time.

Is it possible to "include as link" the files
of the win application in the web application?

Note that I am clearly aware that it is possible to
reference a DLL. I am asking something different.

I would like to be able to "see" the source code files
of the win from the web application application so that
if I make a change to a source file, that change will be
there for the win application too.

Does anyone know how can I reference (as links, not copy)
the files of the win app from the web app ??

The add existing project does not seem to have a "link" option (or I do
not see it) .
It seems to me that there was one in the 2003 version.
