The error's a bit difficult to understand to be honest. I wont copy/paste the entire strack trace here, but here's how it goes
An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is: System.InvalidOperationException: An exception was thrown in a call to a WSDL export extension: System.ServiceModel.Description.DataContractSerializerOperationBehavior contract: Silverlight.ESRIMapping:ESRIMappingService ----> System.Runtime.Serialization.InvalidDataContractException: Type 'System.Windows.Input.TouchDevice' cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute. If the type is a collection, consider marking it with the CollectionDataContractAttribute. See the Microsoft .NET Framework documentation for other supported types. at System.Runtime.Serialization.DataContract.DataContractCriticalHelper.ThrowInvalidDataContractException(String message, Type type) ..... .....
what you said does make sense. Currently, I'm trying to declare a serializable class where I have all the properties as in IdentifyResult, but skip the symbol because I don't need it here...
nvm. Along the way, I had been trying to serialize a map itself. How brave and stupid 😛
