Summary
Most feeds are going to be accessed across domains. This means that a feed’s domain must contain a cross-domain policy file that permits the feed to be accessed by the Silverlight client’s hosted server’s domain. If the cross-domain policy file does not exist on the hosted domain’s server, you can use services that support open cross-domain policies, such as FeedBurner, Yahoo! Pipes, and Popfly, to effectively relay the feed to the Silverlight client application.
Silverlight 2 applications can read RSS and Atom feeds using
WebClient or HttpWebRequest and can consume them
using the SyndicationFeed class, LINQ
to XML, or the XmlReader. The
SyndicationFeed class offers the most
features for the least amount of work, as it encapsulates a lot of the
functionality required to read and manage feed data, which is
effectively a form of POX.
This chapter demonstrated how to consume feeds, mash them together, and work around the lack of cross-domain policy files. The next chapter discusses how to use ADO.NET Data Services and its RESTful style to communicate with Silverlight 2.
