How to use logging to NET core Console Application that uses Dependency Injection

Question

I have a project .Net Core in React and, to save time, I would like to test a method to export files by a Console Application. But I can't to implement the DI in my console, here's the error:

Unable to resolve service for type 'Microsoft.Extensions.Logging.ILogger`1[MyPrj.Managers.Managers.Implementations.MyLogManager]' while attempting to activate 'MyPrj.Managers.Managers.Implementations.MyLogManager'.

This is a simplified version of my Program.cs:

class Program
{
    public static IConfigurationRoot Configuration;
    public static ServiceProvider serviceProvider;

    public static void Main(string[] args)
    {
        var services = new ServiceCollection();
        var builder = new ConfigurationBuilder()
            .SetBasePath(Path.Combine(AppContext.BaseDirectory))
            .AddJsonFile("appsettings.json", optional: true);

        Configuration = builder.Build();

        services.AddDbContext<MyDBContext>(options => options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

        services.Configure<MailOptions>(Configuration.GetSection("EmailSettings"));
        [... other options...]

        services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
        services.AddSingleton<ILogManager, MyLogManager>();

        services.AddScoped<IMailManager, MailManager>();
        [... other services ...]
        services.AddScoped<IDocumentationManager, DocumentationManager>();

        serviceProvider = services.BuildServiceProvider();

        MainAsync().GetAwaiter().GetResult();

        Console.WriteLine("END");
        Console.ReadKey();
    }

    private static async Task MainAsync()
    {
        await ExportAsync();
    }

    public static async Task ExportAsync()
    {
        using (MyDBContext dbContext = serviceProvider.GetService<MyDBContext>())
        {
            List<User> user = dbContext.Users.ToList();
            
            var logger = serviceProvider.GetService<ILogManager>();
            var docManager = serviceProvider.GetService<IDocumentationManager>();
            
            string userAnswer = Console.ReadLine();

            var file = await docManager.GetUser(userAnswer);

            File.WriteAllBytes("C:\tmp\user.txt", file.File);
        }
    }
}

Thanks to all, it has been enough adding services.AddLogging(), following @Steven 's advice, to solve my problem.
