adding nlog to .net core 3.0

Question

adding nlog to .net core 3.0 application results in

'IServiceCollection' does not contain a definition for 'ConfigureLoggerService' and no accessible extension method 'ConfigureLoggerService' accepting a first argument of type 'IServiceCollection' could be found (are you missing a using directive or an assembly reference?)

for Nuget I have

NLog.Extensions.Logging v1.6.1
NLog.Web.AspNetCore v4.9.0

in startup.cs

 public Startup(IConfiguration config)
        {
            LogManager.LoadConfiguration(String.Concat(Directory.GetCurrentDirectory(), "/nlog.config"));
            Configuration = config;
        }

public void ConfigureServices(IServiceCollection services)
        {
            services.AddAuthentication(IISDefaults.AuthenticationScheme);
            services.AddMvc();
            services.AddTransient<ICwopaAgencyFileRepository, CwopaAgencyFileRepository>();
            services.AddTransient<ICurrentUserRepository, CurrentUserRepository>();
            services.AddTransient<IUserRepository, UserRepository>();
            services.AddTransient<IRevenueReceivedRepository, RevenueReceivedRepository>();
            services.AddTransient<ILesseeRepository, LesseeRepository>();
            services.AddTransient<ITractLesseeJunctionRepository, TractLesseeJunctionRepository>();
            services.AddTransient<IPadRepository, PadRepository>();
            services.AddTransient<IWellRepository, WellRepository>();
            services.AddTransient<IWellOperarationRepository, WellOperationRepository>();
            services.AddTransient<IRoyaltyRepository, RoyaltyRepository>();
            services.AddTransient<IRoyaltyAdjustmentCardViewModelRepository, RoyaltyAdjustmentCardViewModelRepository>();
            services.AddSingleton<ILoggerManager, LoggerService>();
            string conString = Configuration["ConnectionStrings:DefaultConnection"];
            services.AddDbContext<DataContext>(options =>
                options.UseSqlServer(conString));
            services.ConfigureLoggerService();
            services.AddMvc(option => option.EnableEndpointRouting = false);
            services.AddMemoryCache();
            services.AddSession();
        }

Do you have a main NLog package? It is a part of NLog.Extensions.Logging, but their GitHub says about NLog package. Please, share your csproj file — Pavel Anikhouski
ConfigureLoggerService is not a method from NLog. Think you are using some broken tutorial. Try look here instead: github.com/NLog/NLog/wiki/Getting-started-with-ASP.NET-Core-3 — Rolf Kristensen

if you're following this tutorial, don't forget add this method extension

public static void ConfigureLoggerService(this IServiceCollection services)
{
    services.AddSingleton<ILoggerManager, LoggerManager>();
}

because you're calling it in this line

services.ConfigureLoggerService();

Also, you can considere removing it, because you're registering this service LoggerService with the interface ILoggerManager.
