HttpClientFactory for console application

HttpClientCoreSapmle.cs

using System.Net.Http;
using Microsoft.Extensions.DependencyInjection;

namespace ConsoleApp1
{
    // Install-Package Microsoft.Extensions.DependencyInjection
    // Install-Package Microsoft.Extensions.Http

    class HttpClientCoreSapmle
    {
        internal void Execute()
        {
            var httpClient = new ServiceCollection()
                .AddHttpClient()
                .BuildServiceProvider()
                .GetService<IHttpClientFactory>()
                .CreateClient();

            var html = httpClient.GetStringAsync("https://twitter.com/ko_ro_chin").Result;
        }
    }
}

Nice simple example. Works in test project too.
