我正在关注本教程:https://andrewlock.net/using-dependency-injection-in-a-net-core-console-application/

并相应安装了包,但日志不会在任何地方打印.

这是我的代码:

  var serviceProvider = new ServiceCollection()
            .AddLogging()
            .AddTransient<IFoo, Foo>(s =>
            {
                return new Foo()})
            .BuildServiceProvider();

            //configure console logging
            serviceProvider
                .GetService<ILoggerFactory>()
                .AddConsole(LogLevel.Debug);

 var logger = serviceProvider.GetService<ILoggerFactory>().CreateLogger<Program>();

            logger.LogError("Starting application");
