Heres example for log4net:

1. Create a new console project called Log4NetTest
   
2. Add log4net [1.2.13] nuget package into project
   

3. Write following program:
   

   using System.Threading.Tasks;
   using log4net;
   using System.Text;
   using System.CollectionsGeneric;
   using System;
   namespace Log4NetTest
   {
       class Program
       {
   
           private static readonly ILog _logger = LogManager.GetLogger("testApp.LoggingExample");
   
           static void Main(string[] args)
           {
               // Configure from App.config. This is marked as obsolete so you can also add config into separate config file
               // and use log4net.Config.XmlConfigurator method to configure from xml file.            
               log4net.Config.DOMConfigurator.Configure(); 
   
               _logger.Debug("Shows only at debug");
               _logger.Warn("Shows only at warn");
               _logger.Error("Shows only at error");
   
               Console.ReadKey();
           }
       }
   }
   

4. Change your app.config to following:
   

5.Run application and you should find following file from bin\Debug folder:

2013-12-13 13:27:27,252 [8] DEBUG testApp.LoggingExample (null) - Shows only at debug
2013-12-13 13:27:27,280 [8] WARN  testApp.LoggingExample (null) - Shows only at warn
2013-12-13 13:27:27,282 [8] ERROR testApp.LoggingExample (null) - Shows only at error
