We recently started a project under the link http://arslie8ws.codeplex.com for Silverlight 2.0 based Arabic Internet Explorer 8 Web Slices. These slices could be downloaded and modified to fit the needs of Arabic websites. The initial set of web slices include a News Slice that reads from RSS feeds of newspapers, Stock Data Slice that reads information from a stock feed an provides graphical information and a Airline Reservation Slice.
We are planning to customize the slices for local sites and put the code here for immediate consumption.
Special thanks to Emad Abdelaziz our Silverlight MVP for putting these samples together.
