Die Serilog-Dateisenke protokolliert nicht in der erwarteten Datei, wenn ReadFrom.Configuration(configuration) fehlt ⇐ C#

[Anonymous]

Ich versuche, die Serilog-Dateisenke basierend auf der Dokumentation in meiner ASP.Net Core 2.2-Anwendung zum Laufen zu bringen. Ich kann in meiner Anwendung keine Protokolle sehen.
Was fehlt mir?

Program.cs:

Code: Select all

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Serilog;
using System;

namespace Scrubber
{
public class Program
{
private static string _environmentName;

public static void Main(string[] args)
{
try
{
var iWebHost = CreateWebHostBuilder(args).Build();
var configuration = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{_environmentName}.json", optional: true, reloadOnChange: true)
.Build();

var logger = new LoggerConfiguration()
.ReadFrom.Configuration(configuration.GetSection("Serilog"))
.CreateLogger();
Log.Logger = logger;
Log.Information("Application starting");
iWebHost.Run();
}
catch(Exception exception)
{
Log.Error(exception.ToString());
}
finally
{
Log.CloseAndFlush();
}
}

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.ConfigureLogging((hostingContext, config) =>
{
//config.ClearProviders();
_environmentName = hostingContext.HostingEnvironment.EnvironmentName;
})
.UseStartup();
}
}

Appsettings.development.json:
