Visual InterDev was the first IDE I ever used outside of notepad.
It was bundled in with one Microsofts early webediting tools with office (97/200)....but not FrontPage.
I thought I was touching the future, it was so amazing! I really don't remember much about other than the impression that it left on me.
n.b. I worked on the Visual Studio Core team, which maintained devenv.exe, among other things, from 2003-2007'ish.
