Error while consuming Github API V3 using Httpclient or even Httpwebrequest

Question

I’m unable to consume the Github V3 API with basic authentication (without using Octokit). I know it works with Restsharp but I want to know why it doesn’t work with HttpClient and HttpWebRequest.

I always get the same answer :

"A protocol breach error occurred"

Just follow my code:

using (var client = new HttpClient())
{
    var response = client.GetAsync("https://api.github.com/emojis").Result;

    if (response.IsSuccessStatusCode)
    {
        var responseContent = response.Content; 
        string responseString = responseContent.ReadAsStringAsync().Result;

        Console.WriteLine(responseString);
    }
}

Answer 1

To use Httpclient recommend using async and await for the calls, which makes the code efficient for external calls, I performed a test and it worked, follow the code, remembering that it was necessary to inform a Header.

public async Task GetGithub(){
      using (var client = new HttpClient())
      {
        client.DefaultRequestHeaders.Add("User-Agent", "Other");

        var response = await client.GetAsync("https://api.github.com/emojis");

        if (response.IsSuccessStatusCode)
        {
            var responseContent = response.Content; 
            string responseString = await responseContent.ReadAsStringAsync();

            Console.WriteLine(responseString);
        }
    }
}
