 As always when frontend is separated from backend, we have to deal with CORS. But I prefer to have one single URL for frontend + backend and get rid of CORS problem by simply call under `/api` path. Moreover, it'll be production ready without need to manage any `Vite` variable for API URL and we'll get HTTPS provided by dotnet. Back to API project.
 
+For convenience, let's change the randomly generated ASP.NET ports by predefined ones:
