**Then**, add `UseSerilog()` to the web host builder in `BuildWebHost()`.
**Then**, add `UseSerilog()` to the Generic Host in `CreateHostBuilder()`.

```csharp
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
public static IHostBuilder CreateHostBuilder(string[] args) =>
Host.CreateDefaultBuilder(args)
.ConfigureWebHostDefaults(webBuilder =>
{
webBuilder.UseStartup<Startup>();
})
.UseSerilog(); // <-- Add this line;
}
```

**Finally**, clean up by removing the remaining configuration for the default logger:

* Remove calls to `AddLogging()`
* Remove the `"Logging"` section from _appsettings.json_ files (this can be replaced with [Serilog configuration](https://github.com/serilog/serilog-settings-configuration) as shown in [the _EarlyInitializationSample_ project](https://github.com/serilog/serilog-aspnetcore/blob/dev/samples/EarlyInitializationSample/Program.cs), if required)
* Remove `ILoggerFactory` parameters and any `Add*()` calls on the logger factory in _Startup.cs_
* Remove `UseApplicationInsights()` (this can be replaced with the [Serilog AI sink](https://github.com/serilog/serilog-sinks-applicationinsights), if required)

That's it! With the level bumped up a little you will see log output resembling:
