I'm trying to call RoleEnvironment.GetConfigurationSetting("SOMEKEY") like so:

public partial class AzureBasePage : System.Web.UI.Page
{
    protected ChargifyConnect Chargify
    {
        get {
            if (this._chargify == null) {
                this._chargify = new ChargifyConnect();
                this._chargify.apiKey = RoleEnvironment.GetConfigurationSettingValue("CHARGIFY_API_KEY");
            }
            return this._chargify;
        }
    }
    private ChargifyConnect _chargify = null;
}

My ServiceConfiguration.cscfg key looks like this:

<Setting name="CHARGIFY_API_KEY" value="AbCdEfGhIjKlMnOp" />

And I get this error:
