Local IIS treating Framework ASP.NET as Core application

I'm having the static content issue where I get 404s on images and CSS. I've gone through all the standard fixes.

One thing I found was that moving my Git repo into the wwwroot folder, worked. My coworker said this was how Core apps were done. I had installed Core to work on a separate application a month or two back, and it always worked fine. But then when I went back to the Framework 4.6.1 ASP.NET app, it no longer worked locally for debugging. If I publish to a server, it's fine.

I have since uninstalled VS 2017 Pro as well as everything Core related. Reinstalled VS with a coworkers config. Removed IIS feature from Windows, rebooted, added it back with all the same settings as my coworkers.

Does anyone know if there is some config VS is using that is confusing IIS into thinking my Framework webapp is Core?
