connection string

hi, i was just wondering what's wrong with my code. i have class library to handle all the classes of my asp.net project. when im compiling a class, i am getting an error "Error 1 The name 'ConfigurationManager' does not exist in the current context " . i have this code for that error message:

string connStr = ConfigurationManager.ConnectionStrings["ConnString"].ConnectionString;

im not sure about this because im new in asp.net. am i missing a reference here?if yes, what namespace should i include? by the way, i tested this directly in my asp.net age and it is working fine. when i use visual c#.net, that's where the error prompts me, and i cant build that class library.

Make sure this is referenced in the cs file:

using System.Configuration;
