missing vb.net reference

Hi experts,

I am writing a web application in asp.net using visual basic and am trying to include some external code called NeatUpload that allows multiple files to be uploaded at a time.  I’ve followed the instructions but get errors when I build as follows:

      error CS0234: The type or namespace name 'Xpath' does not exist in the namespace 'System.Xml' (are you missing an assembly reference?)

My web.config file is as follows and I’ve gone to website, add reference and selected System.Xml from the .net tab yet I still get the error.   Can anyone tell me what I’m doing wrong?

Here’s the namespaces excert from my web.config file.

      <pages>
                  <namespaces>
                        <clear/>
                        <add namespace="System"/>
                        <add namespace="System.IO"/>
                        <add namespace="System.Collections"/>
                        <add namespace="System.Collections.Generic"/>
                        <add namespace="System.Collections.Specialized"/>

It's case sensitive, it should say "System.Xml.XPath" rather than "System.Xml.Xpath"

Is System.Xml listed under the project references.

If not, right click on the project, choose Add Reference, and add a reference to System.Xml.dll.

Carl,

The web.config does say System.Xml.XPath, doesn't it or have I missed something?

The one you posted has a lower case "p" in it, or was that a type when posting?

Carl,

Thanks for your help, you've answered the question, it solved the problem for the system.xml.xpath and will get the points however, I still have one problem left.

                        <add namespace="System.Core"/>

error CS0234: The type or namespace name 'Core' does not exist in the namespace 'System' (are you missing an assembly reference?)

Am I doing a similar thing, can you help?

Thanks for your help.  The system.core no longer exists so I just deleted it and it works.
