Task-based async example

Awaiting asynchronous work

using System.Net.Http;

static async Task<string> FetchAsync(string url)
{
    using var client = new HttpClient();
    return await client.GetStringAsync(url);
}

var content = await FetchAsync("https://example.com");
Console.WriteLine(content.Length);
