inject Cookies to AngleSharp

I need AngleSharp read a cookie session to get open a secure website, i try this but it is not working.

req.Credentials = new NetworkCredential("user", "pass","domain");
var response = (HttpWebResponse)request.GetResponse();
var statusCode = response.StatusCode;
if (statusCode == HttpStatusCode.OK)
{
    var configuration = Configuration.Default.WithCookies().WithDefaultLoader();
    var context = BrowsingContext.New(configuration);
   await context.OpenAsync(url);
}

But i obtain 401(not authorised) from server. How can i achieve this?

WithRequesters is an extension in AngleSharp.Io package.

THNX, but unfortunately it’s supporting only net45 now. I hope it’ll be fixed soon - https://github.com/AngleSharp/AngleSharp.Io/issues/9
