ConfigurationSettings problem?

[Bruce W.1]

I started a new web app.. In my Page_Load method I do this:

string strConnTxt = ConfigurationSettings.AppSettings["ConnectString"];

and the compiler gives this error:

The type or namespace name 'ConfigurationSettings' could not be found
(are you missing a using directive or an assembly reference?)

This is a very basic thing but I can't figure out why it is happening.
Does anyone know?

Thanks for your help.
