Hi Team,

When the automation is going under Wait for document validation and resume activity then it is throwing an exception as mentioned below:

RemoteException wrapping System.Runtime.Serialization.InvalidDataContractException: Type ‘System.Net.Mail.AlternateViewCollection’ 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.AsyncResult.End[TAsyncResult](IAsyncResult result)
at System.Activities.WorkflowApplication.IdleEventHandler.OnStage2Complete(IAsyncResult lastResult, WorkflowApplication instance, Boolean isStillSync)
at System.Activities.WorkflowApplication.EventFrame(IAsyncResult result)

However, while running the code in Debug mode and applying a breakpoint on this activity and when it comes to this stage then I validate the results in orchestrator and continue the process then it is not giving any exception.

Please let me know how to resolve this error ASAP.

HI @Gupta_Divya ,

Wait for resume activity should be in the Main xaml file. If it is invoked in any other workflow, u will face the serialization error

Hi Soorya,

I am using it in Main xaml only.
