HttpClient do not support Progress Reporting

The best way to go is using Windows.Web.Http.HttpClient instead of System.Net.Http.HttpClient. The first one supports progress.

I don't find an event DownloadProgressChanged in HttpClient in msdn

Try using webclient for DownloadProgress. Difference between httpclient vs webclient

If you still need a httpclient to Progress Reporting you need to implement yourself .Progress Bar with HttpClient

I think you should use WebClient instead of HttpClient

WebClient client = new WebClient ();
    Uri uri = new Uri(address);

    // Specify that the DownloadFileCallback method gets called 
    // when the download completes.
    client.DownloadFileCompleted += new AsyncCompletedEventHandler (DownloadFileCallback2);
    // Specify a progress notification handler.
    client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(DownloadProgressCallback);

Event handler

private static void DownloadProgressCallback(object sender, DownloadProgressChangedEventArgs e)
{
// Displays the operation identifier, and the transfer progress.
Console.WriteLine("{0}    downloaded {1} of {2} bytes. {3} % complete...", 
    (string)e.UserState, 
    e.BytesReceived, 
    e.TotalBytesToReceive,
    e.ProgressPercentage);
}
