[mono-android] How to detect and handle FaultException returned rom WCF

[Nirban Dutta]

Hi Jon,



I could not catch FaultException returned from WCF calls, instead it is always caught as Serialization Exception as given below:





{System.Runtime.Serialization.SerializationException: Expected element 'ExceptionDetail' in namespace 'http://schemas.datacontract.org/2004/07/System.ServiceModel', but found Element node 'InvalidRequestFault' in namespace 'http://schemas.datacontract.org/2004/07/PC.WcfService'

For the same reason, I cannot analyse the FaultCode to take necessary action from the android application
