How "WebApplication.CreateBuilder()" method configures default logging Providers.

Question

How the "WebApplication.CreateBuilder()" method configures logging.

In ASP.NETCORE GitHub page "https://github.com/dotnet/aspnetcore/blob/main/src/DefaultBuilder/src".

I can see the "ConfigureLogging" code is only enabled within WebHost.CreateDefaultBuilder() method.

But I am calling ""WebApplication.CreateBuilder()" and it returns "WebApplicationBuilder" object.

And even in WebApplicationBuilder class I am not able to find where these logging providers called.

Can anyone explain the flow how "WebApplication.CreateBuilder()" method configures default logging Providers.

see line 256:

https://github.com/dotnet/aspnetcore/blob/main/src/DefaultBuilder/src/WebApplicationBuilder.cs#L256

it configures and adds logging as a service. many components are configured to call logging if the service is configured.

note the default logger is the console logger
