Our software has been around for a long time. It started life as an ASP application, with all the database logic tucked away in VB6 components, and lots and lots of ASP pages. Because we invested so much into these VB6 components and also the ASP UI infrastructure, we're still using it today - so we have ASP pages that call VB6 components. Obviously, as we move more and more of the code into .NET, we are relying on Interop more and more to allow us to make use of "new" stuff from existing ASP pages...
