As a simple example, say I have an eCommerce application. An order is submitted and various notifications emails are sent (to the person ordering, to the administrator, etc).
public ActionResult SubmitOrder()
{
SubmitOrder();
SendNotifications();
Return View("OrderSubmitted");
}
I don't want the user to wait while the SendNotifications function is executing. Essentially, I want it to behave as if I called it using Ajax from the view.
How would I accomplish this?
If you want your action to be async you can convert your ActionResult into async Task this will behave like ajax call from view.
Ex.
public Task<ActionResult> SubmitOrder()
{
var tasks = await Task.WhenAll(SubmitOrder, SendNotifications);
return view("OrderSubmitted", tasks );
}
Something that you need to take note is you also need to convert your methods (SumitOrder/SendNotifications) to be async or use Task.Run like what @phnkha mentioned. Also this need v4.5 or if you are targeting v4.0 you need Microsoft.Bcl.Async package.

Optional approach you can also use Hangfire for this kind of task.
