Question Custom Appconfig does not load.

[groadsvb]

I have some custom configs in my appconfig file but I get an error when I try loading int with the configurationManager getsection method. This is the message "Unrecognized element 'MiscFields'."
loading the setting:

  _zollPcrSetting = System.Configuration.ConfigurationManager.GetSection("EnRoute/ZollPCRSettings")

This is the appconfig

<?xml version="1.0"?>

I solved problem with the custom appconfig loading

I think that I removed the property "properties" which overrides the base property and now everything loads. There may really be an issue with the way I structured everything in the ZollPCRSetting class but by not overriding that property it loads now.

       Protected Overrides ReadOnly Property Properties() As System.Configuration.ConfigurationPropertyCollection
            Get
                Return _properties
            End Get
        End Property
