问题
I found this but I don't have an angular cli file so I tried to install with npm and then add it with import statement in my wwwroot/css/style.css file but that didn't work either.
EDIT: My project is an Angular 4 App With Asp.Net Core 2.0 Web API so the suggested tutorial was unable to resolve the issue.
