Here, I am trying to make the logging with nlog simple step 1. install required packages (Console/UI layer) Install-Package NLog.Extensions.Logging -Version 1.6.1 //And Install-Package NLog.Web.AspNetCore -Version 4.9.0 step 2. In your console project at root , create nlog.config (add-->new item-->web configuration file) name it as nlog.config and paste below code "1.0" encoding= "utf-8" ?> "http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi= "http://www.w3.org/2001/XMLSchema-instance" autoReload= "true" internalLogLevel= "Info" > "NLog.Web.AspNetCore" /> "File" name= "allfile" fileName= "1nlog-sharpencode-${shortdate}.log" layout= "${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" /> "*" minlevel= "Trace" writeTo= "allfile" /> now, suppose you have 2 layers BLL and DAL, add those to the DI container, after creating the container as follow class Program { static void Main(string[] args) { var services = new ServiceCollection(); ConfigureServices(services); using (ServiceProvider serviceProvider = services.BuildServiceProvider()) { MyDAL app = serviceProvider.GetService (); MyBLL app1 = serviceProvider.GetService (); app.Run(); } } private static void ConfigureServices(ServiceCollection services) { services.AddTransient (); services.AddTransient (); services.AddLogging(builder => { builder.SetMinimumLevel(LogLevel.Information); builder.AddNLog( "nlog.config" ); }); } } now, use to log in BLL/DAL as using Microsoft.Extensions.Logging; using System; namespace YourNamespace { public class MyDAL { private readonly ILogger _logger; public MyDAL(ILogger logger) { _logger = logger; } public void Method() { try { // save here } catch (exception ex) { _logger.LogInformation(ex.ToString()); } } } }
