Some month ago, I faced some weird bugs in VSCode with extension stop working (no reference, no completion, no occurrence). I don't know how it was possible that it has ever work before as the fix was to launch VSCode in a shell with the environment being set, via a batch file:

@echo off
call "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" x86_amd64
start "" code %*

So RLS has the proper MS tools to work with.

It's not very convenient nor straightforward and I'm opening this issue to try to improve RLS on this matter.

Any thought?
