Serilog–How to enable Seq integration through config?

I’m a big fan of structured logging in general and Serilog in particular. Especially in combination with Seq it is unbeatable.

Today I lost some time searching how to specify the Seq log sink using configuration. Here are the steps I had to take:

• Add the Serilog.Settings.Configuration NuGet package to your project(this one is for ASP.NET Core, others exists for web.config, …)
• Create a LoggerConfiguration:

	public class Startup
	{
	public Startup(IConfiguration configuration)
	{
	Configuration = configuration;
	ConfigureLogging();
	}
	public IConfiguration Configuration { get; }
	private void ConfigureLogging()
	{
	var loggerConfig = new LoggerConfiguration()
	.ReadFrom.Configuration(Configuration);
	Log.Logger = loggerConfig.CreateLogger();
	}
	}

• After that you can specify your configuration inside your appsettings.json:

	"Serilog": {
	"Using": [ "Serilog.Sinks.Seq" ],
	"MinimumLevel": {
	"Default": "Information",
	"Override": {
	"Microsoft": "Warning",
	"System": "Warning"
	}
	},
	"WriteTo": [
	{
	"Name": "Seq",
	"Args": { "serverUrl": "http://localhost:5341" }
	}
	],
	"Enrich": [ "FromLogContext", "WithMachineName", "WithThreadId" ],
	"Properties": {
	"Application": "AppName",
	"EnvironmentName": "Dev"
	}
	}
