Post does not return

[DarthSonic]

This is our code:

public static void SendBackendNotification(string channel, string username, string actiontext, string emoji)
        {
            var slackClient = new SlackClient(ConfigurationManager.AppSettings["SLACK_WEBHOOK_URL_CM_NOTIFICATIONS_NEW"]);
            var slackMessage = new SlackMessage
            {
                Channel = channel,
                Username = username,
                Text = actiontext,
                IconEmoji = emoji
            };
            try
            {
                slackClient.Post(slackMessage);
            }
            catch (Exception slackException)
            {
                AiLogger.Log(slackException, new HttpContextWrapper(HttpContext.Current), false, false);
            }
        }

slackClient.Post(slackMessage); does not return to code and does not throw exception. It sends the message but request is pending until timeout occurs (ASP.NET MVC) or we end the application.

With release version 1.0.6 it works, with 1.1.0 or later it does not work.

How can we fix that?

• channel is "#test_errors" and exists
• username is "Testuser"
• actiontext is "Foo"
• emoji is Emoji.Exclamation
• slackMessage is "Foo"

Hey Sven, apologies for this - Sounds very much like an issue we had way back regarding mixing blocking/async calls which resulted in setting .ConfigureAwait(false) on the HttpClient calls. This was then discussed in Issue #60

I've pushed a potential fix for this which you could try out here: https://github.com/mrb0nj/Slack.Webhooks/packages/42275 and let me know if this resolves your issue?

Thx, that works!
