Serilog ReadFrom Configuration

I configured like this

public static void Main(string[] args)
{
    var _config = new ConfigurationBuilder()
                .AddJsonFile("loggerconfig.json") //mantained separate config file
                .Build();

    Log.Logger = new LoggerConfiguration()
                .ReadFrom.Configuration(_config)
                .CreateLogger();

    CreateWebHostBuilder(args).Build().Run();
}

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .UseSerilog()
        .UseStartup<Startup>();

and this is the better way according to Serilog.

I configure it like that:

return WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>()
            .UseSerilog((hostingContext, loggerConfiguration) => loggerConfiguration
                .ReadFrom.Configuration(hostingContext.Configuration))
            .Build();

by default Serilog look for Serilog section in configuration
