VB.Net 2005 Custom configuration section

[Kalisto]

Ive got the following in my Ap.Config

<configSections>
    <section name="messageQueueHandlers" 
    type="CustomQueueHandler, MyHandlers.CustomQueueHandler"/>
  </configSections>

and further on down in the same config file is the node that starts the custom section.

Ive added a new project to my solution with the Default Namespace set to MyHandlers.CustomQueueHandler and defined the code.

Added the Project Reference to my startup application

Yet when I attemot to execute

System.Configuration.ConfigurationManager.GetSection("messageQueueHandlers")

I get a "Cannot find assembly or file MyHandlers.CustomQueueHandler"

Ive checked, and the dll is created and is being stored in the bin folder of the application, so what am I doing wrong?
