How To Upgrade Bootstrap in ASP.NET Core Web Applications - Blazor, MVC, Razor Pages, etc.

All ASP.NET Core web apps come with Bootstrap 5 built-in. However, it is not set up to upgrade using npm or NuGet. So let's look at how to upgrade to the latest Bootstrap 5 version in MVC, Razor Pages, Blazor Server, and Blazor WebAssembly. We will even look at how to fix an upgrade issue.

Thanks! I am learning so much!
Newbies like me: if you dont see any effect after implementing these changes try to clear the browser's cache (Strg+F5); that did help me on my Wasm project (17:00).

If we have many pages in our website and we have used bootstrap everywhere. And bootstrap plans to change the many of its class names then what will happen? Is there a way to handle such kind of broad change?

Thanks Tim, good video
Do you have a tutorial also for .NET Core 8 and default Blazor Web App. Seems tricky
Any reason you dont att it as a Nuget ? i thought that was the best way to keep things up to date

Hey i'm learning about Libman and was woundering why you didn't update the versions that was as its also pretty easy, It would be nice to get a video to see if those changes will also be needed

I'm surprised there's not a tool in visual studio that will automatically replace the files, similar to the package manager (where bootstrap can also be found).

Can you do a video on signalr authentication to a blazor server. Preferably using a Maui app.

What about replacing css and js files in our catalogs, huh?

So a 24 minute video on how to copy two links and lose all the ability to edit the bootstrap.css in any way that makes sense.... this feels like it pretty much defeats the point of updating bootstrap at all
