I suspect this is very simple, but I searched and didn't find and/or didn't understand. I'm working on a Razor Pages app to learn web dev, and I'm trying to put a navbar in the _Layout.cshtml, but while the default declaration of it works fine, if I change it to "navbar-inverse" bootstrap class then it doesn't work any more. I thought if it might be the version of bootstrap, and I then installed the latest (bootstrap 5) as a Nuget package. What I would need now is how to reference the new version 5 of bootstrap in my _Layout.cshtml file (<link rel="..." and <script src="...") and I want to reference from the file system (or whatever it is that works). Also I would like you to confirm if actually the problem in my code is because of the bootstrap old version. The navbar with "navbar-inverse" class doesn't work and before with a default class it did.
