I use Visual Studio Express instead of Monodevelop, as I'm sure plenty of people do. To get Intellisense working in VS, I've been following these steps in the past: http://forum.unity3d.com/threads/how-do-i-get-intelli-sense-in-visual-studio.118475/ Not a very elegant way to do it, but it works - or at least it did until recently. For some reason, my project files are no longer showing up in new projects in Unity. So I can't open my unity-csharp.sln file. It's not that the files are hidden, they just aren't there. Is it that a new version of Unity no longer uses them? Why could this be happening? The files are there for my old projects, it's just newly created ones that are affected. Edit: By the way, I'm using VS Express and Windows 8. I'm downloading the new VS "Community" now.
