Serilog - Config through appsettings

Here is appsettings.json

{
  "Logging": {
    "LogLevel": {
      "Default": "Warning",
      "Hangfire": "Information"
    }
  },
  "AllowedHosts": "*",
  "Environment": "Development",
  "Serilog": {
    "Using": [
      "Serilog.Sinks.Console",
      "Serilog.Sinks.File"
    ],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Microsoft": "Warning",
        "System": "Warning"
      }
    },
    "WriteTo": [
      {
        "Name": "Console"
      },
      {
        "Name": "File",
        "Args": {
          "path": "//SDD-IIS1/_inout$/hangfire/Log-.txt",
          "rollingInterval": "Day"
        }
      }
    ]
  }

}

Here is program.cs

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

namespace Hangfire_Web
{
    public class Program
    {
        
        public static void Main(string[] args)
        {
            var configuration = new ConfigurationBuilder()
                    .SetBasePath(Directory.GetCurrentDirectory())
                    .AddJsonFile("appsettings.json")
                    .Build();

            Log.Logger = new LoggerConfiguration()
                .ReadFrom.Configuration(configuration)
                .CreateLogger();

            try
            {
                Log.Information("Starting web host");
                CreateHostBuilder(args).Build().Run();
            }
            catch (Exception ex)
            {
                Log.Fatal(ex, "Host terminated unexpectedly");
            }
            finally
            {
                Log.CloseAndFlush();
            }

        }


        public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .UseSerilog()
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
}

There’s a nuget library called Serilog.Settings.Configuration that can be used to read the configuration from appsettings.json.
