Unable to resolve ILogger from Microsoft.Extensions.Logging

Question

I\'ve configured my console application\'s Main like so

var services = new ServiceCollection()
                .AddLogging(logging => logging.Add

I am assuming you are using the default template for .net core web application.
In your your Startup.cs you should have a method like this↓↓↓↓↓↓↓

// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
    services.Configure(options =>
        {
            // This lambda determines whether user consent for non-essential cookies is needed for a given request.
            options.CheckConsentNeeded = context => true;
            options.MinimumSameSitePolicy = SameSiteMode.None;
        });


        services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
        //Do the service register here and extra stuff you want
         services.AddLogging(config =>
        {
            config.AddDebug();
            config.AddConsole();
            //etc
        });

    }

Edit: I have written a simple program for you to show how it works

public class MyClass
{

    private readonly ILogger _logger;


    public MyClass(ILogger logger)
    {
        _logger = logger;
    }
    public void MyFunc()
    {
        _logger.Log(LogLevel.Error, "My Message");
    }
}



public class Program
{
    public static void Main(string[] args)
    {
        var services = new ServiceCollection().AddLogging(logging => logging.AddConsole());
        services.AddSingleton();//Singleton or transient?!
        var s = services.BuildServiceProvider();
        var myclass = s.GetService();
     }
}

Edit: Output of the program:
