Switching From a BackgroundWorker To a Task - It's a Neater Solution, Particularly When Reporting Progress

I've used BackgroundWorkers for a long time - most of my apps use them to free up the UI from long running tasks, and they have a built in progress reporting mechanism which a "raw" Thread lacks. But I've recently realized that the Task class can do it as well, and in a really tidy way. So this tip shows you the old and new ways, so you can easily switch.
