If you install the Windows version of Mono (which currently supports .NET 3.5; they're working on 4.0), Wine can use it instead of .NET. See http://wiki.winehq.org/Mono Wine ships with some registry keys and files that installers check to decide whether .NET is present. This is so that they do not insist on installing .NET if you prefer to use Mono. This should ideally be a complete .NET replacement, but at the moment it's very incomplete and what is there usually doesn't work very well. Beating Wine and Mono into shape would be a lot of work, and very little work is going into it currently. Still, if your software doesn't work in Wine with Mono installed, you can file a bug.
