namespace ConsoleLoggerSample
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create a logger factory with a console provider
            using ILoggerFactory loggerFactory = LoggerFactory.Create(builder => builder.AddConsole());

            // Create a logger with the category name of the current class
            ILogger<Program> logger = loggerFactory.CreateLogger<Program>();

            // Log some messages with different log levels and message templates
            logger.LogTrace("This is a trace message.");
            logger.LogDebug("This is a debug message.");
            logger.LogInformation("Hello {Name}!", "World");
            logger.LogWarning("This is a warning message.");
            logger.LogError("This is an error message.");
            logger.LogCritical("This is a critical message.");

            // Use structured logging to capture complex data
            var person = new Person { Name = "Alice", Age = 25 };
            logger.LogInformation("Created a new person: {@Person}", person);

            // Use exception logging to capture the details of an exception
            try
            {
                throw new Exception("Something went wrong.");
            }
            catch (Exception ex)
            {
                logger.LogError(ex, "An exception occurred.");
            }

            Console.WriteLine("Press any key to exit.");
            Console.ReadKey();
        }
    }

    // A simple class to demonstrate structured logging
    class Person
    {
        public string Name { get; set; }
        public int Age { get; set; }
    }
