CS0234: The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

Hello Guys,

I have completed a application with visual studio 2010. Now I am facing an issue like below when deploy the application on 2.0 framework server

CS0234: The type or namespace name 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?)

Any idea how to resolve this?
