title: Angular2 asp.net core. What exactly is vendor.css for?
body: <p>I'm a big fan of bootstrap, hailing from the php world. I've recently started on angular2 and asp.net core. I notice a vendor.css file which when opened has bootstrap stuff in it as well.</p>
  
  <p>The npm already has bootstrap installed and there is the bootstrap.min files in the wwwroot lib folder.</p>
  
  <p>I'm confused with this file. What is it for? Isn't it redundant with bootstrap?</p>
