Ok, i've done ALOT of research since I first read this question and although a top answer did get picked already, I felt I owed it to everyone else that was transitioning from Visual Studio/.NET/Windows to Linux and felt lost as I did -- thanks to arscariousus for his answer to get me going in the right direction.
First off, MonoDevelop is the program of choice if you are looking for the nearest 1:1 intellisense. In fact, using MonoDevelop 4.0, it almost looks like Visual Studio in many ways. I was very suprised that nobody was talking more about this until I found out one problem: there was no MonoDevelop 4 package for linux of any flavor, just windows (BAH!). I was discouraged but found that i COULD use it because all I had to do was download the source for 4.0 and compile it (took about an hour give or take) but when it was done, it works great.. I have successfully built the Mono 4.0.1 package for Ubuntu Studio 13.04 amd64, if anyone wants it let me know --- i was unable to find a precompiled package but maybe there is one out there, this is probably why other ppl dont suggest it. I spent alot of side-time in Qt, but it sucks learning a new environment if you already know .NET well though QtCreator does seem to be a good MFC via VC++ substitute strictly linux speaking --- but Qtcreator leaves much to be desired for intellisense which is where it falls short. MonoDevelop makes learning the other parts of the gtk toolkit that it encompases much easier and pretty much was exactly what i was looking for. Maybe other ppl dont like it but it is definately best in my opinion.
The Verdict--- MonoDevelop 4.0 hands down because the intellisense is almost exactly like Visual Studio not to mention some of the other features, keybindings, layout, etc.
You can get the source right from their homepage, and gist has some scripts to explain how to make the debian pkgs if you use debian/ubuntu. I'm sure there's probably some gist snippet for your specific l-distro as well. Hope this helps...
