 ```csharp
     // dotnet add package Serilog.Settings.Configuration
-    .UseSerilog((hostingContext, services, loggerConfiguration) => loggerConfiguration
-        .ReadFrom.Configuration(hostingContext.Configuration)
-        .Enrich.FromLogContext()
-        .WriteTo.Console())
+builder.Services.AddSerilog((services, loggerConfiguration) => loggerConfiguration
+    .ReadFrom.Configuration(builder.Configuration)
+    .Enrich.FromLogContext()
+    .WriteTo.Console())
 ```
 
-This has the advantage of making the `hostingContext`'s `Configuration` object available for configuration of the logger, but at the expense of ignoring `Exception`s raised earlier in program startup.

 If this method is used, `Log.Logger` is assigned implicitly, and closed when the app is shut down.
