{
    class Program
    {
        static async Task Main(string[] args)
        {
            using var httpClient = new HttpClient();
            var url = "https://www.example.com";
            var response = await httpClient.GetAsync(url);
            response.EnsureSuccessStatusCode();
            var responseBody = await response.Content.ReadAsStringAsync();
            Console.WriteLine(responseBody);
