无法找到ConsoleLoggerProvider作为类型或命名空间

Question

我在配置我的数据库上下文文件时使用了loggingfactory，在示例练习中他们使用了consoleloggingprovider但是在我的练习中它说我找不到名称或类型，并且在示例练习中没有引用到consolelogginprovider我已检查所有导入，这不是问题。这是我的代码，但它确实不是代码问题，我不知道它可能是什么。

 protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
 {

           var loggerFactory = new LoggerFactory(providers: new[]
        {
              new ConsoleLoggerProvider((category, level)
                    => category == DbLoggerCategory.Database.Command.Name
                       && level == LogLevel.Information, true)
        });

        if (!optionsBuilder.IsConfigured) //only configure the connection if the parameterless contructor was used (no options where provided).
        {
            optionsBuilder.UseSqlServer(ConfigurationManager.ConnectionStrings["LotteryConnectionString"].ConnectionString);
            //TODO: tell EF (Entity Framework) that is going to operate against a SQL Server database using the connection string in the app.config of the UI project
        }
    }
