I'm testing the configuration settings class with VB .Net and have the following configuration file

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <AppSettings>
	<add key="Aplicacion" value="Application's Name" />
	<add key="ConnectionString" value="Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=CNT001;Data Source=ibm600e" />
  </AppSettings>
</configuration>

and I call the settings like this on my application's main sub

       Dim sAppName As String = ConfigurationSettings.AppSettings("Aplicacion")
        Dim sConnString As String = ConfigurationSettings.AppSettings("ConnectionString")

but I'm getting an error message: "Additional information: Unrecognized configuration section AppSettings"

Can anybody tell me what am I doing wrong?

TIA,

Enmanuel
