‘HttpUtility’ does not exist in the current context

Last couple days working I developed a social networking share control for asp.net

http://www.smartwebsource.info/smartshare/Default.aspx

Where i use BitlyApi to shorten my url to send twitter.
There i use BitlyApi class in my App_Code folder . As it is web project so HttpUtility is found from System.Web.dll.
I try to make my SmartSocialShare class library to a dll so i make a new class library .
And paste all my Class file from my App_Code folder in the new Class library project . When i try to build the dll it show this error.

‘HttpUtility’ does not exist in the current context

Then i add System.Web.dll as a reference in my class library then it make my dll without error.
Hopes this will help you to solve this error.
