Customizing Web.Config

[Negative0]

I am trying to add custom nodes to my web.config file and I am running into a few issues. It looks something like this:

<configuration>
    <configSections>
        <section name="MySection" type="MySectionHandler"/>
    </configSections>
 
 
<MySection>
<CustomNode>1</CustomNode>
<CustomNode>2</CustomNode>
<CustomNode>3</CustomNode>
<CustomNode>4</CustomNode>
</MySection>
...
</configuration>

Then I have the code for mysectionhandler as follows:

Public Class MySectionHandler
    Implements IConfigurationSectionHandler
 
    Public Function Create(ByVal parent As Object, ByVal configContext As Object, ByVal section As System.Xml.XmlNode) As Object Implements System.Configuration.IConfigurationSectionHandler.Create
        Return "HELLO"
    End Function
End Class

Finally, I have my code that trys to display the values:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        TextBox1.Text = ConfigurationSettings.GetConfig("MySection")
 
    End Sub

I am getting an error on the Configuration.GetConfig line. The error I am getting is:

Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.

Parser Error Message: Exception creating section handler.

It and it highlights the <section name="MySection" type="MySectionHandler"/> line in the Web.Config file.

Anyone seen this before, or can anyone offer any suggestions?
