Question

User request some page at my website.

What i want to do? Send to user a fast answer and start background task which take a long time.
It looks like:

public ActionResult index()
{
    var task = new Task(Stuff);

    //start task async
    task.start(); 

    return View();
}

public void Stuff()
{
    //long time operation    
}

How can i do it?

Answer 1

You can pass the Task StartNew() method a parameter that indicates the task you’re starting is “long running”, which provides a hint to the Task Scheduler to start the task on a new thread.

var task = Task.Factory.StartNew(Stuff, TaskCreationOptions.LongRunning);
