Creating a form resulting infinite document awaiting from https page about anglesharp.io HOT 6 CLOSED

Hm bit of a strange thing. You post it here, but you did in fact use the DefaultHttpRequester, which is the one from AngleSharp. Are you sure you did not intend to use the HttpClientRequester?

Regarding the question: Potentially the CA verification fails. I'd recommend disabling HTTPS verification to see if this is the issue.

What is HttpClientRequester? I don't see this class in AngleSharp. DefaultHttpRequester is from AngleSharp.Io.

It may be true (haven't checked yet), but why removing Form creating solves this problem (with absolute repeatability)?

You confuse a namespace with a library. The AngleSharp.Io namespace is already in AngleSharp, but this is the AngleSharp.Io library, which brings more requesters such as

Not sure what you refer to. You may run into a deadlock here, but again - from the description you focus on an HTTPS problem. Maybe first check there.

Exactly what I wroted: see steps 1-4 you can reproduce.

I added

ServicePointManager.SecurityProtocol |=
	SecurityProtocolType.Tls12 | 
	SecurityProtocolType.Tls11 | 
	SecurityProtocolType.Tls;

to the start of my code, but it didn't solve my problem. I also tried use HttpClientRequester and have exactly same behavior.

var client = new HttpClient();
client.DefaultRequestHeaders.Add("Accept-Language", "en-US,en;q=0.812");
var requester = new HttpClientRequester(client);
var config = Configuration.Default.WithRequester(requester).WithDefaultLoader();
var context = BrowsingContext.New(config);
var document = await context.OpenAsync(urlAddress);

I also checked the document – response is empty if remove "https://". (I updated the example project)

The only way to get any responce from it is to remove any Froms creating before executing OpenAsync

The thing runs. As written you may run into a deadlock - I'd suggest to ConfigureAwait(false) or similar. In any case this does not seem like a problem with the requester or AngleSharp itself.

This thing runs. Until you execute Form initialisation as I wroted in reproduction steps

ConfigureAwait(false) fixed it, thanks!
