I'm on the hunt for the latest ASP.NET web design templates (using Visual Basic) to update a couple of my websites that were based on an old version of Microsoft's "ASP.NET Web Forms Site" template.
One of the standard project templates offered by VisualStudio 2019 is called "ASP.NET Web Application (.NET Framework)", but it does not appear to contain any descriptive documentation. This template contain a lot of JavaScript files, complex CSS and view switching code that is far from being self-explanatory. The latest version of the "ASP.NET Web Forms Site" template also contains no documentation.
Where can I find sources of guidance on how to use Microsoft's project templates? I've tried searching for such information but without any success.
