Hello @ScarletKuro @henon @danielchalmers, here's a draft PR for updated MudBlazor template projects, made from scratch based on the latest aspnetcore Blazor templates. There's of course a bit of work to do to understand the newer template code, as well as to upgrade pages to use MudBlazor components.

This was PR'ed early so you can see the raw template changes before I dig into upgrading to MudBlazor components and restoring some of the original custom MudBlazor template code.

Also, did you have a workflow to let you quickly test changes as you worked? It looks like I'll need to install templates, make a solution, then run it each time I need to test something. Thanks for the review!
