Hi Gopi Menon,
Attached is a sample project showing you an approach to achieve what you want. If you have further questions feel free to ask.
On a side note, I'd like to inform you that we've just released an online tool that allows you to reduce the size of your Silverilght applications. For more information, please visit http://blogs.telerik.com/blogs/posts/10-06-10/telerik_assembly_minifier.aspx
All the best,
the Telerik team
