The umbraco.IO namespace is located in the businesslogic.dll did you modified the source directly or did you create a seperate project? if you've created a seperate project make sure you reference the assemblies:

• umbraco
• businesslogic
• cms

Cheers,

Richard

I have all three referenced and Visual Studio is not finding the umbraco.io namespace. It finds the others I need.

The code below fails to compile.  The IO in umbraco.IO does not exist in the umbraco namespace.

using System;
using System.Xml;
using umbraco;
using umbraco.BusinessLogic;
using umbraco.cms.businesslogic;
using umbraco.cms.businesslogic.web;

namespace SBA.AZBar
{
 public partial class noNodes : System.Web.UI.Page
 {
  protected void Page_Load(object sender, EventArgs e)
  {
   Server.ScriptTimeout = 100000;
   var cacheFile = umbraco.IO.IOHelper.MapPath("/App_Data/umbraco.config");

   var r = XmlReader.Create(cacheFile, new XmlReaderSettings() { DtdProcessing = DtdProcessing.Ignore });
   var d = new XmlDocument(); d.Load(r);

   var n = d.SelectSingleNode("//root");
   if (n.ChildNodes.Count != 0) return;

   Document.RePublishAll();
   library.RefreshContent(); 
  }
 }
}

Ah I know what happened, thanks Jorge. I the same once with the new install of my machine. I couldn't reference any Umbraco assembly. then I looked at the warnings and noticed that it needed the older (1.0) version of asp.net ajax. When I installed that it worked just fine. Just google on the warning that you see and it will point you to the correct download link.

Hope this helps you both,

Richard 

Thanks Richard, i'll take a look about the ajax issue.

I also noticed that by default my project was not using the 4.0 version of the .NET framework.
