c# - How to Send Mail Async -

i running issue when trying send email async, found out no of post on stackoverflow none of them helpful. have following block of code

public class emailservice : iidentitymessageservice {     public task sendasync(identitymessage message)     {         // plug in email service here send email.          var mailmessage = new mailmessage             ("me@example.com", message.destination, message.subject, message.body);          mailmessage.isbodyhtml = true;          var client = new smtpclient();          client.sendcompleted += (s, e) => client.dispose();         client.sendasync(mailmessage,null);         return task.fromresult(0);     } } 

i got email getting exception when block of code run

an asynchronous module or handler completed while asynchronous operation still pending. 

any suggestion?

use sendmailasync instead of sendasync:

public class emailservice : iidentitymessageservice {     public async task sendasync(identitymessage message)     {         // plug in email service here send email.          var mailmessage = new mailmessage             ("me@example.com", message.destination, message.subject, message.body);          mailmessage.isbodyhtml = true;          using(var client = new smtpclient())         {             await client.sendmailasync(mailmessage);         }     } }
