This is a Visual Studio Code extension, which enables Windows users to open Integrated Terminal with Visual Studio Tools. It is enabled by utilizing vcvarsall.bat on Visual C++ installation.
It also supports Bash on Ubuntu on Windows (WSL) invocation without modifying the existing integrated terminal configuration.
You can select a Visual Studio version upon opening Visual Studio Command Prompt.
Currently, it supports VS2008, VS2010, VS2012, VS2013, VS2015, VS2017, and VS15 Preview.
This will open Bash on Ubuntu on Windows on a new integrated terminal.
NOTE: This feature was once removed from the extension and now back again! I'm now developing a new extension that launches shells of WSL Linux distributions and it will replace the feature in near future.
Of course, the extension runs only on Windows! :(
