AsyncTasks & Scheduling
Asynchronous Method Invocation Introduction In this article, I am going to explain asynchronous method calls and how to use them. After playing with delegates, threads, and asynchronous invocation for so long, it would be a sin not to share some of my wisdom and knowledge on the subject, so hopefully, you won’t be looking at an MSDN article at 1 AM wondering why you decided to go into computers. I will try to use baby steps and lots of examples… Overall, I will cover how to call methods asynchronously, how to pass parameters to such methods, and how to find out when a method completes execution. Finally, I will show the Command Pattern in use for simplifying some of the code.
We're gearing up to begin sending out our email newsletter here at Eggheadcafe.com and so we've been experimenting with different ways to send out a large number of emails to subscribers. Since the SMTP class does not expose an asynchronous version of the SmtpMail.Send(Message) method, (e.g. BeginSend / EndSend) we either have to use a commercial or open source component that does, or roll our own. Fortunately the Framework comes to our rescue here with callback delegates and the BeginInvoke method, which (unfortunately) is only documented by Microsoft for Windows Forms controls (making developers think that that's the only place it's actually available to use).

“It's not that I'm so smart , it's just that I stay with problems longer .” -- Einstein We often get questions about how to provide feedback in an ASP.NET page when something is going on in the background. A lot of times developers get confused about the difference between running a task asynchronously and running a task on a background thread. ASP.NET: Long Running Task with Page Feedback
