Downloading and saving a file Async in Windows Phone 8

Question

How can I download and save a file to IsolatedStorage asynchronously? I used WebClient first for the purpose, but I couldn\'t await till completion

Answer 1

In my opinion best way to use native implementation like this (Wrapping Begin/End asynchronous API):

var url = new Uri(UriString, UriKind.Absolute);
var fileName = Path.GetFileName(url.LocalPath);

var w = WebRequest.CreateHttp(url);
var response = await Task.Factory.FromAsync(w.BeginGetResponse, w.EndGetResponse, null);
await response.GetResponseStream().CopyToAsync(new FileStream(ApplicationData.Current.LocalFolder.Path + @"\" + fileName, FileMode.CreateNew));
