Best thing to do is use Azure Functions. It was designed for exactly this problem. It's actually pretty good. You can run a scheduled task whenever you like using a timer trigger.

Darin is correct, however, if you had to do it in your app, here's how you would go about it:

In Global.asax.cs

    static void ScheduleTaskTrigger()
    {
        HttpRuntime.Cache.Add("ScheduledTaskTrigger",
                              string.Empty, 
                              null, 
                              Cache.NoAbsoluteExpiration, 
                              TimeSpan.FromMinutes(60), // Every 1 hour
                              CacheItemPriority.NotRemovable, 
                              new CacheItemRemovedCallback(PerformScheduledTasks));
    } 

    static void PerformScheduledTasks(string key, Object value, CacheItemRemovedReason reason)
    {
       //Your TODO

       ScheduleTaskTrigger();
    }

    void Application_Start(object sender, EventArgs e)
    {
          ScheduleTaskTrigger();
    }

Ideally, use a Windows Service or a Scheduled Task instead

You could use a System.Timers.Timer. But please notice that implementing recurring background tasks in ASP.NET applications is a perilous task. Don't forget that IIS could recycle the application pool at any time and under some circumstances (period of inactivity on the site, CPU/Memory thresholds are reached, ...) bringing down all background tasks you might have started.

The correct way to do this is to implement it in another application. This could for example be a Windows Service or a simple Console Application scheduled to run at regular intervals with Windows Scheduler.
