Using BackgroundWorker to complete two methods one after the other WPF/C#

Question

In my program I have two methods that takes a while to complete, about few minutes each. While these methods are being executed, I display a Progress Bar in a separate window wh

Answer 1

An option i prefer is to have those 2 methods in a different thread and use a while loop to check if thread is still running and if it is use Task.Delay() EG.

private async void BlahBahBlahAsync()
    {
        Thread testThread = new Thread(delegate () { });
        newThread = new Thread(delegate ()
        {
            Timeconsuming();
        });
        newThread.Start();
        while (testThread.IsAlive)
        {
            await Task.Delay(50);
        }
    }

    private void Timeconsuming()
    {
        // stuff that takes a while
    }
