ASP.Net RSS Toolkit gives ASP.Net applications the ability to consume and publish to RSS feeds.

Features include:

  • {{RssDataSource}} control to consume feeds in ASP.NET applications

    • Works with ASP.NET data bound controls

    • Implements schema to generate columns at design time

    • Supports auto-generation of columns at runtime (via {{ICustomTypeDescriptor}} implementation)

  • Caching of downloaded feeds both in-memory and on-disk (persisted across process restarts)

  • Generation of strongly typed classes for feeds (including strongly typed channel, items, image, handler) based on a feed URL (the toolkit recognizes RSS, Atom and RDF feeds) or a file containing a sample feed. Allows programmatically download (and creation) of feeds using strongly-typed classes.

The toolkit includes:

  • Consuming feeds, using:

    • Stand-alone command line feed compiler that generates VB.Net or C# code files.

    • Build provider for .rssdl file (containing the list of feed URI(s) {"including local files"})

    • Build provider for .rss file (containing feed XML in RSS/Atom/RDF or OPML format)

  • Support for generation of feeds in ASP.NET application including:

    • RSS HTTP handler (strongly typed HTTP handlers are generated automatically by the build providers) to generate the feed.

    • RSS Hyper Link control (that can point to RSS HTTP handler) to create RSS links

    • Optional secure encoding of user name into query string to allow generation of personalized feeds

  • Set of classes for programmatic consumption and generation of RSS feed in a late-bound way, without using strongly types generated classes

How-to(s):

Packaging

The toolkit is packaged as an assembly (DLL) that can be either placed in GAC or in ‘bin’ directory of a web site application. It is also usable from client (including WinForms) applications.

RSS Toolkit works in Medium Trust (RssToolkit.dll Assembly either in GAC or in ‘bin’) with the following caveats:

  • If the ASP.NET application consumes RSS feeds, the trust level must be configured to allow outbound HTTP requests.

  • To take advantage of disk caching, there must be a directory (configurable via AppSettings{""rssTempDir""}) where the trust level policy would allow write access. However, disk caching is optional.

History

  • 6/15/2007 New Release (version 2.0.0.0)

    • Huge revamp of the project by Piyush Shah http://blogs.msdn.com/shahpiyush/default.aspx to support strong-type feed generation. Added support for Atom, RDF. Added OPML aggregation, and schema validation of OMPL sub-feeds. Added ability to serve out feeds as RSS, Atom, RDF or OPML. Now supports qualified namespaces and enclosures. Download manager now can cache to application relative paths (like the App_Data directory of a web site) to aid in medium trust deployments. Added unit tests via Visual Studio Team Foundation test framework.
  • 3/26/2006 Update (version 1.0.0.1)

    • Added MaxItems property to RssDataSource to limit the number of items returned.

    • Added automatic generation of tags from RssHyperLink control, to light up the RSS toolbar icon in IE7. For more information please see http://blogs.msdn.com/rssteam/articles/PublishersGuide.aspx

    • Added protected Context property (of type HttpContext) to RssHttpHandlerBase class, to allow access to the HTTP request while generating a feed.

    • Added generation of LoadChannel(string url) method in RssCodeGenerator so that one strongly typed channel class can be used to consume different channels.

    • Fixed problem expanding app relative (~/…) links containing query string when generating RSS feeds.
