Hi Manish,
I wish I had a Silverlight fruit basket to post, but no one has
developed one yet, as far as I know. If that is something you could do,
I think it would be a valuable contribution to the community. As you
may know, the criteria for a fruit basket program is available on
http://FruitBasketDemos.org
and you can post a solution there as well.
Cheers,
Jamal
