GetRequiredService throw "The logger is already frozen"

I know this is an older issue but passing preserveStaticLogger: true to .UseSerilog(..) solved the issue for me. I have not found a way to get rid of my BuildServiceProvider() call, so this seems to be a way around the System.InvalidOperationException: The logger is already frozen

Host.CreateDefaultBuilder(args)
  .UseSerilog(
      (context, services, configuration) => configuration
          .ReadFrom.Configuration(context.Configuration)
          .ReadFrom.Services(services)
          .Enrich.FromLogContext()
          .WriteTo.Console(),
      true
  )

Hi @benlinx1018 ,

Building IServiceProvider from the IServiceCollection is not a recommended pattern because it can result in multiple constructions and undesired side effects. Use this one instead

services.AddOptions<SwaggerGenOptions>()
    .Configure<IApiVersionDescriptionProvider>((options, provider) =>
    {
        foreach (var avd in provider.ApiVersionDescriptions)
        {
            options.SwaggerDoc(avd.GroupName, CreateMetaInfoApiVersion(avd));
        }
    });

services.AddSwaggerGen();
