Speaking of Visual Studio Addins
During the time that Resharper was broken for my project, I became accustomed to using a program called JustCode! from Axtools. Its an addin for c# similar to Resharper that delivers background compilation for c# projects similar to what goes on in the background of a vb.net project.
I'm terrible at passing around the wrong types & I'm always declaring variables that never get used.... For that its a good help. I don't know that its worth $140 or whatever they're charging for it, but It was a step up from the barebones visual studio 2005 IDE.
