Shopping Client
Otto, the German based largest eCommerce and catalog retailer in Europe released a Vista based shopping client. It provides state of the art shopping experience to the consumers. You can view different products from the catalog and also try them on a model to see how they match and if you like its looks. You can mix and match various pants with shirts, shoes, etc to your satisfaction. If you have not seen it, please go to Otto's web site (www.otto.de) and download the client. Remember it is a Vista client, which means it only works on Vista.
This was built using WPF (Windows Presentation Foundation), CardSpace, WCF (Windows Communcation Foundation) on Vista. Interesting part integration with the back end is done using services built using WCF.
Please try it out and let me know how you like it.
