So I figured out where to install composer packages with VS Tools... I'm curious though if it is possible to run or unpack and use the contao/core-bundle? It's an open source CMS... I installed it, but don't see any of its files... Thanks
Upon installing a composer package, you will see it in the project' References (in the Solution Explorer window).
If you need to see its files, you can enable "Show All Files" (on the top of the Solution Explorer window).
