The links are useful.For a more specific case ,how would you simplify this code below.Can you see the logic for setting and removing the busy indicator is repeated ?

ComponentViewModel.Instance.IsApplicationBusy = true;
ComponentViewModel.Instance.BusyMessage = "Loading...";

var task1 = Task.Factory.StartNew(() => DoTask1());
task1.ContinueWith(antecdent =>
{
ComponentViewModel.Instance.IsApplicationBusy = false;
CustomAction1();
}

Second Instance :

ComponentViewModel.Instance.IsApplicationBusy = true;
ComponentViewModel.Instance.BusyMessage = "Loading...";

var task2 = Task.Factory.StartNew(() => DoTask2());
task2.ContinueWith(antecdent =>
{
ComponentViewModel.Instance.IsApplicationBusy = false;
CustomAction2();
}
