Polling and Cancellation
In this video, the existing application will be modified to add cancellation support. For each HREF link found, a method will be called which will enter into an infinite loop, periodically downloading the HTML content of that link, looking for changes using the TaskEx.Delay method. In addition, a CancellationToken will be passed through each method, allowing the user to cancel out of the process at any time.
