How do I change the Duplicate Detection Window on an existing Windows Azure Service Bus topic?

Question

Is it possible to change the Duplicate Detection Window on an existing Windows Azure Service Bus topic?

I am using C# to interact with Service Bus.

Answer 1

I think you need to set the DuplicateDetectionHistoryTimeWindow
