I don't get startup class file in vs 2022, what should i do

apparently after .net6 startup is not made by default to add the service shown in the videos you could add "builder.Services.AddTransient();" in the program.cs file instead of "services.AddTransient();" in the startup file

More Info button not working on firefox

I am using Dotnet 8.0 and firefox browser. I have followed along the codes using vscode! However, the more info button is not working at my side. I have searched different sites for solution, but nothing is working. The button is not event firing any events

I was able to solve the modal not popping up. The series was made using Bootstrap 4 or before, so if you're using a newer version, you need to change "data-toggle" and "data-target" to "data-bs-toggle" and "data-bs-target" in ProductList.razor
