Windows Phone 7 development: reading RSS feeds

One limitation on Windows Phone 7 is related to System.Net namespace classes. There is no convenient way to read data from web. There is no WebClient class.

The book has also interesting content from the past that is really interesting reading. To understand where you are you should know where you come from.
