Multi-threaded downloader in C#

I'm working on a WPF download manager which should support downloading multiple files at the same time through HTTP, adding a new download, pause/resume, displaying and updating each download process information (filename, size, download percentage, time left...) in a DataGrid, displaying progress in a ProgressBar and a bunch of other stuff.

So, the idea is to use a separate thread for each download process, and be able to dynamically create/cancel threads. What is the best way to accomplish this? Using a BackgroundWorker, ThreadPool?

I would just use Thread directly and keep the references to all the treads that I create.

The WebClient XXXAsync methods such as DownloadFileAsync already provide you with asynchronous versions of all methods that allow you to perform the HTTP requests on separate threads. They are also C# 5.0 async ready.

Since this is a WPF application you should ensure that you are modifying the UI controls only on the main UI thread using the Dispatcher.BeginInvoke method.
