Answer 1

Your main class is MainApplication of type MauiApplication
That means that the template that you used to create that project is old (I think it was preview 6 or 7)
If you create a new .NET MAUI App with a newer template, you will see that the main class is something like this. And it's the only main file
public static class MauiProgram
{
public static MauiApp CreateMauiApp()
{
var builder = MauiApp.CreateBuilder();
builder
.UseMauiApp<App>()
.ConfigureFonts(fonts =>
{
fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
});
return builder.Build();
}
}
So I would recommend creating a new project using a new template, and then migrate the rest of the classes/views (use the same name for your project to make it easier)
