Hi,

This is following on from an earlier thread but the issue has evolved a little.  Basically, I have this code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using umbraco;
using umbraco.presentation;

namespace myproject
{
   public partial class SetCookie : System.Web.UI.UserControl
    {
     protected void Page_Load(object sender, EventArgs e)
      {
         if (library.IsLoggedOn()) {
               Label1.Text = "Logged in";
            } else {
              if (string.IsNullOrEmpty(UmbracoContext.Current.Request.Cookies["visitorGUID"].Value))
                {
                 Guid myguid = Guid.NewGuid();
                 UmbracoContext.Current.Response.Cookies["visitorGUID"].Value = myguid.ToString();
             }
         }

       }
 }
}

However, when I try to build it, it errors, saying "You must add a reference to assembly 'System.Web.Abstractions'".  I've tried adding the namespace reference System.Web.Abstractions but it in turn errors saying "The type or namespace name 'Abstractions' does not exist in the namespace 'System.Web'".  Seems like I can't win ;)

Does anyone know what namespaces to reference in order to get this to work, or is there a more fundamental problem?

Thanks all.
