-Most of the site's functionality works with just the web application running. However, the site's Admin page relies on Blazor WebAssembly running in the browser, and it must communicate with the server using the site's PublicApi web application. You'll need to also run this project. You can configure Visual Studio to start multiple projects, or just go to the PublicApi folder in a terminal window and run `dotnet run` from there. Note that if you use this approach, you'll need to stop the application manually in order to build the solution (otherwise you'll get file locking errors).
