I think this topic has already been discussed but the archives seem really slow today.
I have an app written in vb 6.0 that our customers use. Can we make a change to a vb 6 com dll to call a VB.net dll? If so, how hard is it? Do I use interop? What we are trying to do is have our existing app call a webservice.
