I have a class where I’m using session variables, notwithstanding when I compile Project it’s sending me this error: “Name ‘session’ doesn’t exist in class or namespace ‘WUC_CreDes.Class1’”.
Does it mean that it is not permitted to me using session variables into a class?
This is my code:

using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace WUC_CreDes
{
public class Class1
{
public static bool No_PostBack()
{
Session["par1"] = "";
return false;
}
}
}

Thank you in advance for your help.

A.L.
