Hello we have a Business Logic Layer which has an Email Services Class. In this class we have a method which will create an email(This part works and compiles fine). However when we try to access the app config file in order to test the method we get an error saying - Can't retrieve the app config mail settings and says all values are null when they are not. Here is the app config section for our code:

<mailSettings>
  <smtp deliveryMethod="Network" from="[email protected]">
    <network host="localhost" port="25" defaultCredentials="true"/>
  </smtp>
</mailSettings>

Here is there code we use to connect to the app.config:

private System.Net.Configuration.MailSettingsSectionGroup mailSettings;

SmtpClient client = new SmtpClient(mailSettings.Smtp.Network.Host, mailSettings.Smtp.Network.Port);

What are we doing wrong here?
