0. Create a new ASP.NET Core project

1. Add dependency in csproj manually or using NuGet

<PackageReferenceInclude="NLog.Web.AspNetCore"Version="4.*" /><PackageReferenceInclude="NLog"Version="4.*" />

2. Create a nlog.config file.

<?xml version="1.0" encoding="utf-8" ?><nlogxmlns="http://www.nlog-project.org/schemas/NLog.xsd"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd">      autoReload="true"      internalLogLevel="Info"      internalLogFile="c:\temp\internal-nlog.txt"><!-- enable asp.net core layout renderers-->  <extensions>    <addassembly="NLog.Web.AspNetCore"/>  </extensions><!-- the targets to write to-->  <targets><!-- write logs to file-->    <targetxsi:type="File"name="allfile"fileName="c:\temp\nlog-all-${shortdate}.log"layout="${longdate}|${event-properties:item=EventId_Id}|${level:uppercase=true}|${logger}|${message} ${exception:format=tostring}" /><!-- another file log, only own logs. Uses some ASP.NET core renderers-->    <targetxsi:type="File"name="ownFile-web"fileName="c:\temp\nlog-own-${shortdate}.log"layout="${longdate}|${event-properties:item=EventId_Id}|${level:uppercase=true}|${logger}|${message} ${exception:format=tostring}|url: ${aspnet-request-url}|action: ${aspnet-mvc-action}" />  </targets><!-- rules to map from logger name to target-->  <rules><!--All logs, including from Microsoft-->    <loggername="*"minlevel="Trace"writeTo="allfile" /><!--Skip non-critical Microsoft logs and so log only own logs-->    <loggername="Microsoft.*"maxlevel="Info"final="true" /><!-- BlackHole without writeTo-->    <loggername="*"minlevel="Trace"writeTo="ownFile-web" />  </rules></nlog>

3. Enable copy to bin folder

  <ItemGroup>    <ContentUpdate="nlog.config"CopyToOutputDirectory="PreserveNewest" />  </ItemGroup>

4. Update program.cs

usingNLog.Web;usingMicrosoft.Extensions.Logging;publicstaticvoidMain(string[]args){// NLog: setup the logger first to catch all errorsvarlogger=NLog.LogManager.Setup().RegisterNLogWeb().GetCurrentClassLogger();try{logger.Debug("init main");CreateWebHostBuilder(args).Build().Run();}catch(Exceptionex){//NLog: catch setup errorslogger.Error(ex,"Stopped program because of exception");throw;}finally{// Ensure to flush and stop internal timers/threads before application-exit (Avoid segmentation fault on Linux)NLog.LogManager.Shutdown();}}publicstaticIWebHostBuilderCreateWebHostBuilder(string[]args)=>WebHost.CreateDefaultBuilder(args).UseStartup<Startup>().ConfigureLogging(logging=>{logging.ClearProviders();logging.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Trace);}).UseNLog();// NLog: setup NLog for Dependency injection

5. Configure appsettings.json

{"Logging": {"LogLevel": {"Default":"Trace","Microsoft":"Information"        }    }}

6. Write logs

usingMicrosoft.Extensions.Logging;publicclassHomeController:Controller{privatereadonlyILogger<HomeController>_logger;publicHomeController(ILogger<HomeController>logger){_logger=logger;}publicIActionResultIndex(){_logger.LogInformation("Index page says hello");returnView();}

7. Example Output
