Sendgrid-csharp: stuck on await client.SendEmailAsync(msg)
Issue Summary
it seems that SendEmailAsync is not returning (stuck on await).
this is the code i am using:
static async Task Execute(string fromName, string fromEmail, string subject, string message, string text, IEnumerable<string> recipients, int? dealId, int? userId, int? dealType, string category = "", string eventType = "", List<ReplacementTag> replacementtags = null, bool unsubscribe = false, bool bccAdmin = false, bool disableAnalytics = false)
{
string apiKey = ConfigurationManager.AppSettings["SendgridKey"];
dynamic client = new SendGridClient(apiKey);
var msg = new SendGridMessage();
foreach (var recipient in recipients)
{
msg.AddTo(new EmailAddress(recipient));
}
if (replacementtags != null)
{
foreach (var tag in replacementtags)
{
foreach (var v in tag.Val)
{
LoggingProvider.LogAudit(tag.Key + " : " + v);
msg.AddSubstitution(tag.Key, v);
}
}
}
msg.AddTo(new EmailAddress(ConfigurationManager.AppSettings["AdminEmail"]));
msg.From = new EmailAddress(fromEmail, fromName);
msg.ReplyTo = new EmailAddress(fromEmail, fromName);
msg.Subject = subject;
var categories = new List<string>();
if (category != "")
{
msg.AddCategory(category);
}
else
{
msg.AddCategory("User " + userId.ToString());
msg.AddCategory("Campaign " + dealId.ToString());
}
//Add the HTML and Text bodies
msg.AddContent("text/plain", text);
msg.AddContent("text/html", message);
msg.AddCustomArg("orig_send_time", DateTime.Now.ToString());
if (dealId != null)
{
msg.AddCustomArg("dealid", dealId.ToString());
}
if (userId != null)
{
msg.AddCustomArg("userid", userId.ToString());
}
if (dealType != null)
{
msg.AddCustomArg("dealtype", dealType.ToString());
}
if (eventType != "")
{
msg.AddCustomArg("eventtype", eventType);
}
var trackingSettings = new TrackingSettings();
var clickTracking = new ClickTracking()
{
Enable = true,
EnableText = false
};
trackingSettings.ClickTracking = clickTracking;
var openTracking = new OpenTracking()
{
Enable = true
};
trackingSettings.OpenTracking = openTracking;
var ganalytics = new Ganalytics()
{
Enable = false
};
trackingSettings.Ganalytics = ganalytics;
msg.TrackingSettings = trackingSettings;
LoggingProvider.LogAudit("email v9 before send: \n" + msg.Serialize());
var response = await client.SendEmailAsync(msg);
LoggingProvider.LogAudit("email v9 send " + subject + ": " + response.StatusCode);
}
public static void SendMailThread(string fromName, string fromEmail, string subject, string message, string text, List<string> recipients, int? dealId, int? userId, int? dealType, string category = "", string eventType = "", List<ReplacementTag> replacementtags = null, bool unsubscribe = false, bool bccAdmin = false, bool disableAnalytics = false)
{
Execute(fromName, fromEmail, subject, message, text, recipients, dealId, userId, dealType, category, eventType, replacementtags, unsubscribe, bccAdmin, disableAnalytics).Wait();
}
the log message "email v9 before send" is printed but "email v9 send" is not
this is the output of the msg.serialize() :

Hello @lebamb2,
I see a few issues:
dynamic client = new SendGridClient(apiKey);should bevar client = new SendGridClient(apiKey);-- no need to use dynamic any moremsg.From-->msg.SetFrommsg.ReplyTo-->msg.SetReplyTomsg.Subject-->msg.SetSubject- For setting Click Tracking:
msg.SetClickTracking - For setting Open Tracking:
msg.SetOpenTracking - For setting Google Analytics:
msg.SetGoogleAnalytics
Please make these updates and let me know your result.
Thank you!

Changing
var response = await client.SendEmailAsync(msg);
to
var response = await client.SendEmailAsync(msg).ConfigureAwait(false);
resolved this issue for me.

@thinkingserious i made those changes and got the same result.
@bvirkler setting .ConfigureAwait(false) worked!!
can anyone explain why SendEmailAsync is not returning when ConfigureAwait is set to true?
thanks!!

Hi @lebamb2,
Thanks for the follow up! Here is the article it seems like everyone points to with regards to ConfigureAwait: http://blog.stephencleary.com/2012/07/dont-block-on-async-code.html
@bvirkler,
Thanks for sharing the solution!
