每当我smtpClient.SendAsync(...)从ASP.NET MVC应用程序中调用时,异步请求都会自动取消,即使SendAsyncCancel()从未调用过.

.Send(...)另一方面,同步请求通过就好了.

我的EmailService服务包装器处理SmtpClient从我的ASP.NET MVC 3应用程序中发送异步电子邮件.通过StructureMap将服务实例注入到每个MVC控制器中,StructureMap将新SmtpClient实例包装在using (...) { }语句中.

这是我的EmailService.SendAsync包装方法SmtpClient:

public void SendAsync(EmailMessage message)
{
    try

        {

                                {
                                    Subject = message.Subject,
                                    Body = message.Body
                                };

            smtpClient.SendAsync(mailMessage, message);

            _logger.Info(string.Format("Sending async email to {0} with subject [{1}]", …
