        builder
            .UseMauiApp<App>()
            .ConfigureFonts(fonts =>
            {
                fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");

Answer 1

in C# if a method has a non-void return type it means that the method must return an instance of that type.

Which in this case:

public static MauiApp CreateMauiApp()

It is of type MauiApp . If you look at the default CreateMauiApp method created by the template, the last line is

return builder.Build();
