Vista - c++ without /clr

Hi.

I would like to be able to call functions that exist in a class library that
is referenced as a project reference from a C++ console application.

I've got a 40000+ line C++ app that doesnt use the .net framework. Most of
the code was written in a manner to support compiling across different
platforms (unix/windows/etc...) so it isn't /clr friendly. We're scrapping
that requirement in this next release.

I wrote a VB.NET class library.

I want to be able to call the methods from the class library from the C++
app. When I add the /clr compile option, the project brings up thousands of
compile errors.... I don't want to rewrite the entire C++ app all at once
to accomidate these errors, so I've got to find a different way to call the
functionality from the vb.net class library from C++.

An alternate option that one of my coworkers brought up was to register the
vb.net assembly in COM and then call the COM object from C++... but I also
don't want to persue that road because doing so would force me to reregister
the assembly in COM every time I updated the assembly.

Is there another way to call the methods that exist in my vb.net project
from C++?

Thanks,

JRF
