Just a reminder to younger crowd Visual Studio had all this before (packaged in single app hence well-integrated and easy to install) probably for 15 years or longer.
Are you referring to the VS debugger and msvsmon? The VS debugger is an excellent tool, but stopping the world each step is different than how the Clojure REPL setup described by the parent works.
Did/do people really develop applications interactively in VS other than in F# Interactive? I've been using VS a long time for VB6 and C#, only in edit/compile/execute-debug mode.
Interactive Lisp development with Emacs has been around longer than that. The first commit for SLIME, which is a (third-generation, I think) Lisp development environment for emacs, is from September 2003: https://github.com/slime/slime/commit/2fb4c4e53b59ed7b6e5f55... (and the comment implies that there was development before then).
Visual Studio has been around since 1997 (which is pretty cool!). Emacs has been around since 1976, although I don't know how far back it got a decent Lisp development environment. Early 80s, maybe?
