YES. Arshad is correct. Silverlight is a client-side API and SqlClient classes runs on server. The way you can access data in Silverlight applications are using LINQ or Web Services (or WCF).

Hi there. You can not use the sqlclient directly in the silverlight application. its only for client purpose. for that you need to use web services to acces the data layer. even i am not much more knowledge about that. but i am very much sure that we can not directly use. sql n all. you try to add the reference in Silverlight application you will get to know. it does not show the .net assembly it only shows the silverlight assembly.
