C#

Documentation says[^]:

If the server does not send the size of the downloaded file (such as in the case of a passive FTP connection), ProgressPercentage may always be zero.

I are Troll

static void UpdateAvailable()
{
    WebClient wbCheckUpdates = new WebClient();
    wbCheckUpdates.DownloadProgressChanged += new DownloadProgressChangedEventHandler(wbCheckUpdates_DownloadProgressChanged);
    wbCheckUpdates.DownloadDataCompleted += new DownloadDataCompletedEventHandler(wbCheckUpdates_DownloadDataCompleted);
    string webServerURL =
        @"http://download.wikimedia.org/simplewiktionary/20090801/simplewiktionary-20090801-pages-articles.xml.bz2";

    wbCheckUpdates.DownloadDataAsync(new Uri(webServerURL));
}

static void wbCheckUpdates_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
    Console.WriteLine("Download progres: " + e.ProgressPercentage);
}

static void wbCheckUpdates_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
{
    // byte[] result = e.Result;
    Console.WriteLine("Completed");
}

static void Main(string[] args)
{
    UpdateAvailable();
    Console.ReadKey();
}

The DownloadDataAysnc does show progress.

private void DownloadDataCallback (Object sender, DownloadDataCompletedEventArgs e)
{
   // If the request was not canceled and did not throw
   // an exception, get the result.
   if (e.Error == null && !e.Cancelled)
   {
     byte[] data = e.Result;
   } 
   else
   {
     //error or cancelled
   }
}
