Adding Serilog as a service to Generic Host .NET8

Logging is an important part of any application. It helps to understand in and out of the application. I’ve created a simple program to use Serilog with the .NET 8 generic host IHostApplicationBuilder.

Packages required

<PackageReference Include="Microsoft.Extensions.Hosting" Version="8.0.0" />
<PackageReference Include="Serilog" Version="4.0.2" />
<PackageReference Include="Serilog.Extensions.Hosting" Version="8.0.0" />
<PackageReference Include="Serilog.Formatting.Compact" Version="3.0.0" />
<PackageReference Include="Serilog.Settings.Configuration" Version="8.0.2" />
<PackageReference Include="Serilog.Sinks.Console" Version="6.0.0" />

Program.cs

using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Serilog;

namespace Memory
{
    internal class Program
    {
        static async Task Main(string[] args)
        {
            var builder = Host.CreateApplicationBuilder(args);

            var configuration = new ConfigurationBuilder()
                    .SetBasePath(Directory.GetCurrentDirectory())
                    .AddJsonFile("appsettings.json")
                    .Build();

            builder.Services.AddSerilog(config =>
            {
                config.ReadFrom.Configuration(builder.Configuration);
            });

            builder.Services.AddSingleton<Worker>();

            IHost host = builder.Build();

            var worker = host.Services.GetRequiredService<Worker>();
            await worker.ExecuteAsync();
        }
    }
}

Worker.cs, here we have injected the logger.

using Microsoft.Extensions.Logging;

namespace Memory
{
    public class Worker(ILogger<Worker> logger)
    {
        public async Task ExecuteAsync()
        {

            logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
            await Task.Delay(1_000);
            
        }
    }
}

Loaded configuration from the appsettings.json

{
  "Serilog": {
    "Using": [ "Serilog.Sinks.Console" ],
    "MinimumLevel": "Debug",
    "WriteTo": [
      {
        "Name": "Console",
        "Args": {
          "formatter": "Serilog.Formatting.Compact.CompactJsonFormatter, Serilog.Formatting.Compact"
        }
      }
    ],
    "Enrich": [ "FromLogContext" ],
    "Properties": {
      "Application": "Memory"
    }
  }
}
