Portable edition of MSBuild – Extract from VS Build Tools 2015 (can be run from USB with some registry redirection using RegLoadAppKey).
Portable Git – For version control.
Portable editor – VS Code, Notepad++, or Sublime Text.

Carry all source code and .vcxproj / .sln files on USB.
On target machine, run a script that:
