在ASP.NET Core2中记录记录器服务初始化之前发生的异常的正确方法

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
    WebHost.CreateDefaultBuilder(args)
        .ConfigureLogging((hostingContext, logging) =>
        {
            logging.ClearProviders(); // 清除默认的日志提供程序
            logging.AddConsole(); // 添加控制台日志提供程序
            logging.AddDebug(); // 添加调试日志提供程序
            logging.AddEventSourceLogger(); // 添加事件源日志提供程序
        })
        .UseStartup<Startup>();

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.AddTransient<MyService>(); // 注册需要记录异常的服务类

    // 将ILoggerFactory注入到需要记录异常的类中
    services.AddSingleton<ILoggerFactory>(loggerFactory =>
    {
        var serviceProvider = services.BuildServiceProvider();
        var logger = serviceProvider.GetRequiredService<ILogger<MyService>>();
        return loggerFactory.AddProvider(new MyLoggerProvider(logger));
    });
}

public class MyLoggerProvider : ILoggerProvider
{
    private readonly ILogger _logger;

    public MyLoggerProvider(ILogger logger)
    {
        _logger = logger;
    }

    public ILogger CreateLogger(string categoryName)
    {
        return _logger;
    }

    public void Dispose()
    {
    }
}
