using Microsoft.Extensions.Configuration;

class Program
{
    static void Main()
    {
        // Build a configuration object from environment variables
        IConfiguration config = new ConfigurationBuilder()
            .AddEnvironmentVariables()
            .Build();
        
        // Read configuration values
        Console.WriteLine($"Server: {config["Server"]}");
        Console.WriteLine($"Database: {config["Database"]}");
    }
}
