Call GitHub REST API using HttpClient

GitHubRestCall.cs

WebRequestHandler handler = new WebRequestHandler()
{                
  UseProxy = true,                                    
};

var client = new HttpClient(handler);
client.BaseAddress = new Uri("https://api.github.com/");

// You should set the version so that GitHub knows what API you area calling
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/vnd.github.v3+json"));

// You must set a user agent so that the CRLF requirement on the header parsing is met.
// Otherwise you will get an excpetion message with "The server committed a protocol violation. Section=ResponseStatusLine"
client.DefaultRequestHeaders.UserAgent.Add(new System.Net.Http.Headers.ProductInfoHeaderValue("Mozilla", "5.0"));

// Set this to the URL you want.
var response = client.GetAsync("users/bellacode/repos").Result;
