Bear in mind though that VS Express (the free one) doesn't support plugins so if you are that hung-up on Visual Assist, you are out of luck.
That said (and also without yet trying Qt Creator) I don't think there is an IDE that comes even close for Windows even without VA, and I would also point out that Intellisense has got unbelievably better in VS 2010. For me personally, it is as effective as it has always been for C# in VS now.
Yeah, I'm starting to think that this was a futile attempt. All I have at the moment is a laptop and I don't like dual-booting so Linux was sort of a backseat idea...I just like the idea of cross-platform development (plus I AM looking for a reason to go to linux full-time, VS is one of the few things besides games that holds me back). While I did say I was too poor to afford the student license of VA. the student part still provides the advantage of free licenses to VS 2010 Ultimate, so plugins are not a problem and I am certainly aware of how good the intelisense has gotten! It's hard to find a decent answer through google, so I was just hoping maybe someone would have something I'm not aware of that would help cope with the loss.
It's just....well for those of you who've experienced Visual Assist I need not say this but, it's really hard to go back!
Edit: What about CodeLite? Anyone have an experience with that? A lot of these seem like just vanilla IDEs that offer next to nothing in terms of incentive to switch from other vanilla IDEs, it's no wonder I haven't heard of most of them.
