Getting started with ASP.NET Core 2
ℹ️ Missing the trace/debug logs in .NET Core 2? Check your appsettings.json
ℹ️ See also example in GitHub
ℹ️ ASP.NET Core ver. 1 -> go here
.NET 4.6+ or .NET standard 2 are required
How to use for ASP.NET Core with csproj (VS2017 only)
In Visual Studio 2017.
Install the latest:
- NLog.Web.AspNetCore 4.5+
- Update the NLog package if possible
in csproj:
<PackageReference Include="NLog.Web.AspNetCore" Version="4.5.4" />
<PackageReference Include="NLog" Version="4.5.4" />Create nlog.config (lowercase all) file in the root of your project.
We use this example:
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
autoReload="true"
internalLogLevel="info"
internalLogFile="c:\temp\internal-nlog.txt">
<!-- enable asp.net core layout renderers -->
<extensions>
<add assembly="NLog.Web.AspNetCore"/>
</extensions>
<!-- the targets to write to -->
<targets>
<!-- write logs to file -->
<target xsi:type="File" name="allfile" fileName="c:\temp\nlog-all-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${message} ${exception:format=tostring}" />
<!-- another file log, only own logs. Uses some ASP.NET core renderers -->
<target xsi:type="File" name="ownFile-web" fileName="c:\temp\nlog-own-${shortdate}.log"
layout="${longdate}|${event-properties:item=EventId_Id}|${uppercase:${level}}|${logger}|${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-->
<logger name="*" minlevel="Trace" writeTo="allfile" />
<!--Skip non-critical Microsoft logs and so log only own logs-->
<logger name="Microsoft.*" maxLevel="Info" final="true" /> <!-- BlackHole without writeTo -->
<logger name="*" minlevel="Trace" writeTo="ownFile-web" />
</rules>
</nlog>More details of the config file are here.
If you like to include other targets or layout renderers, check the Platform support table, as there is a limited set implemented. Check the column NetStandard. To read more about NetStandard, see the docs from Microsoft
Enable copy to bin folder for nlog.config

or edit .csproj file manually and add:
<ItemGroup>
<Content Update="nlog.config" CopyToOutputDirectory="PreserveNewest" />
</ItemGroup>Update the program.cs
add using NLog.Web; and using Microsoft.Extensions.Logging;
public static void Main(string[] args)
{
// NLog: setup the logger first to catch all errors
var logger = NLog.Web.NLogBuilder.ConfigureNLog("nlog.config").GetCurrentClassLogger();
try
{
logger.Debug("init main");
BuildWebHost(args).Build().Run();
}
catch (Exception ex)
{
//NLog: catch setup errors
logger.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();
}
}
public static IWebHostBuilder BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.ConfigureLogging(logging =>
{
logging.ClearProviders();
logging.SetMinimumLevel(Microsoft.Extensions.Logging.LogLevel.Trace);
})
.UseNLog(); // NLog: setup NLog for Dependency injectionThe Logging configuration specified in appsettings.json overrides any call to SetMinimumLevel. So either remove "Default": or adjust it correctly to your needs.
{
"Logging": {
"LogLevel": {
"Default": "Trace",
"Microsoft": "Information"
}
}
}Remember to also update any environment specific configuration to avoid any surprises. Ex appsettings.Development.json
Inject the ILogger in your controller:
using Microsoft.Extensions.Logging;
public class HomeController : Controller
{
private readonly ILogger<HomeController> _logger;
public HomeController(ILogger<HomeController> logger)
{
_logger = logger;
}
public IActionResult Index()
{
_logger.LogInformation("Index page says hello");
return View();
}When starting the ASP.NET Core website, we get two files:
