Launch Task periodically

Question

I want to launch a method in a separated thread periodically (every minute). I was using System.Timers.Timer but I realize that Timers cause memory leaks.

I need to remove Timers and use task. The first idea is launch a Task in the following way:

_taskWork = Task.Factory.StartNew( DoWork );

And in the DoWork method:

private void DoWork()
{
    While(true)
    {
        // Stuff here

        Thread.Sleep(60000);
    }
}

Is there any way to launch a task avoiding this approach?

You shouldn't use `Thread.Sleep` with tasks, instead use `await Task.Delay(60000);`, and make your method async. Also, you probably shouldn't be using `Task.Factory.StartNew`, instead, after making your method `private async Task DoWork()`, simply call it. — Lasse V. Karlsen, Mar 08 '19 at 07:51
Timers are *designed* for this use case. *Misuse* of timers may have led you to having a memory leak but that would have been about *your code*, not timers themselves. Unfortunately, you've not shown us the code that "causes memory leaks". — Damien_The_Unbeliever, Mar 08 '19 at 07:54
checkout `hangfire` to execute code periodically(cron jobs). (https://www.hangfire.io/) — Aarif, Mar 08 '19 at 08:02

Similar Method : The async equivalent is a while loop with Task.Delay (which internally uses a System.Threading.Timer):

public async Task PeriodicFooAsync(TimeSpan interval, CancellationToken cancellationToken)
{
    while (true)
    {
        await FooAsync();
        await Task.Delay(interval, cancellationToken)
    }
}

This Work fine for me please refer this for more understanding.
