Upgrading to .NET 6 -ASP0014 warning

In preparation of a GraphQL workshop I'm giving later this week, I was updating my demos to .NET 7. The original demos were written in .NET 5, but with the introduction of minimal API's in .NET 6 I decided to take that route. So I removed my Startup.cs file and copied everything inside my Program.cs file:

This however resulted in the following error message(which is in fact a warning but I have 'Treat Warnings as Errors' enabled in Visual Studio):

Angular --deploy-url and --base-href

As long you are running your Angular application at a root URL (e.g. ) you don’t need to worry that much about either the ‘--deploy-url’ and ‘--base-href’ parameters. But once you want to serve your Angular application from a server sub folder(e.g. ) these parameters become important. --base-href If you deploy your Angular app to a subfolder, the ‘--base-href’ is important to generate the correct routes. This parameter will update the <base href> tag inside the index.html. For example, if the index.html is on the server at /angularapp/index.html , the base href should be set to <base href="/angularapp/"> . More information: --deploy-url A second parameter that is important is ‘--deploy-url’. This parameter will update the generated url’s for our assets(scripts, css) inside the index.html. To make your assets available at /angularapp/, the deploy url should
