Is there an implementation of some kind of managed asynchronous thread?

Question

WPF

It is necessary to execute the thread asynchronously, in this thread there must be a time delay that needs to be changed. The thread must: run; stop; pause with the option to continue.

Answer 1

So start a thread and perform a cyclic operation in it.
1. If you need to complete, check the variable

while (isActiveThread)
{
 // действие
}

2. If you want to stop, enter an Event (eg ManualResetEvent ).
or over time

event.WaitOne(1000); // Ждем сигнального или 1 сек.

Answer 2

If you use TPL, then for example this is possible.

async Task Foo() {}

async Task Foo2()
{
  var task = Foo();
  
  if (await Task.WhenAny(task, Task.Delay(1000)) == task)
  {
    // задача успела выполниться за таймаут
  }
  else
  {
    // задача не успела выполниться за таймаут
  }
}
