Hi Sreelakshmi, I can confirm the WSDL matches what you state, however, when pulling this in Visual Studio as a service reference I see no mention in the Reference.cs file of an RuleItemGroup object.
public partial class Rule : object, System.ComponentModel.INotifyPropertyChanged { private RuleItem[][] groupsField; This is a code snippet from the auto compiled Reference.cs and as you can see the groupsfield property is a multi-dimensional array of RuleItem objects. There is no mention of the RuleGroup object i would expect. public partial class Rule : object, System.ComponentModel.INotifyPropertyChanged { private RuleItem[] groupsField; My work around is to remove the second set of brackets from the groupsfield. This fixes the issue with serialising the incoming response from Adwords. The only issue with this work around is everytime I update the service reference it adds the second set of brackets into the groups field property. -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog and Google+: https://googleadsdeveloper.blogspot.com/ https://plus.google.com/+GoogleAdsDevelopers/posts =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API Forum" group.
