How do I debug externally with Visual Studio?

[solidstate1991 via Digitalmars-d-debugger]

I use VSCode since it has better D support, however until I make 
mago-mi usable (it doesn't even support all the commands 
currently it claims, --args seems to be completely broken) or 
find again a working copy of LLDB for Windows (doesn't want to 
compile with Mingw also being installed), I cannot really debug.

The only way I can debug programs is to attach to them after they 
have started, however it's very clunky to use this way, some 
programs even execute too fast to do this way.
