Did anyone try the official MS Lua for Visual Studio extension? https://github.com/Microsoft/VSLua
Visual Studio Extension for Lua is a free, open source plugin that turns Visual Studio into a Lua development environment. It is designed, developed, and supported by Microsoft and the community.
The extension currently supports editing intelliSense, syntax colorization, formatting, and error squiggles. It also supports single Lua file debugging.
It looks a bit broken, but if it makes sense, I can try to leverage my/King connections to resurrect it. I see a magic keyword “debugging” =]
