AngleSharp.Io extends AngleSharp with powerful requesters, caching mechanisms, and storage systems. It is coupled more strongly to the underlying operating system than AngleSharp itself. Therefore it has stronger dependencies and demands and cannot be released for the standard framework (4.6). Nevertheless, it is released as a .NET Standard 2.0 library.

If you just want to use all available requesters provided by AngleSharp.Io you can do the following:

var config = Configuration.Default
    .WithRequesters() // from AngleSharp.Io
    .WithDefaultLoader(); // from AngleSharp

This will register all requesters. Alternatively, the requesters can be provided explicitly. They are located in the AngleSharp.Io.Network namespace and have names such as DataRequester.

To get improved cookie support, e.g., do

var config = Configuration.Default
    .WithTemporaryCookies(); // Uses memory cookies

or if you want to have persistent cookies you can use:

var syncPath = $"Environment.GetFolderPath(Environment.SpecialFolder.UserProfile)\\anglesharp.cookies";
var config = Configuration.Default
    .WithPersistentCookies(syncPath); // Uses sync cookies against the given path

Alternatively, the new overloads for the WithCookies extension method can be used.

AngleSharp.Io offers you the possibility of a simplified downloading experience. Just use WithStandardDownload to redirect resources to a callback.

In the simplest case you can write:

var config = Configuration.Default
    .WithStandardDownload((fileName, content) =>
    {
        // store fileName with the content stream ...
    });

Alternatively, use WithDownload, which allows you to distinguish also on the provided MIME type.

The IHtmlInputElement interface now has AppendFile to easily allow appending files without much trouble.

document
    .QuerySelector<IHtmlInputElement>("input[type=file]")
    .AppendFile("c:\\example.jpg");

More overloads exist.

Furthermore, the IUrlUtilities interface now has DownloadAsync.

document
    .QuerySelector<IHtmlAnchorElement>("a#download-document")
    .DownloadAsync()
    .SaveToAsync("c:\\example.pdf");

The SaveToAsync (as well as the CopyToAsync) are extension methods for the IResponse interface.

• New requesters
  • HTTP (using HttpClient)
  • FTP
  • Supporting data URLs
  • Supporting file URLs
  • Enhanced support for about: URLs
• WebSockets (mostly interesting for scripting engines, e.g., JS)
• Storage support by providing the IStorage interface
• Improved cookie container (AdvancedCookieContainer)
• Enhanced download capabilities for resources / links
