Bring back the old Blazor Templates

Is your feature request related to a problem? Please describe the problem.

I have been working with Blazor for a while, but I am confounded at the lack of templates in .Net8/9, that used to exist earlier. For example, I have been trying to create an ASP.Net Core hosted Webassembly app with EntraID authentication. This has proven to be so much more difficult. The only recourse appears to be to start with .Net 7 template, and then upgrade it to .Net 8.

The current "Blazor Web App" template is extremely confusing...There is a wwwroot folder both in the server and client applications. And the weather page has hard-coded data in it. So basically, there is no guidance on:

1. how to create an app with Entra Id auth
2. api starter code (controller or minimal api)
3. separation of client-side code in the client app. there are components in both server and client app

Describe the solution you'd like

Please help by either providing a clear, concise example or better yet, fix the "Blazor Web App" which is currently unusable.

Additional context

Need to bring back Blazor templates that previously existing in .Net 7.

I would like to see the 'ASP.NET Core Hosted' option return to the Blazor WebAssembly Standalone App template.

+1.

Having to go to a .NET 7 version then upgrade everything to 8 then 9 is... frustrating.
