Assembly: Microsoft.ServiceBus (in Microsoft.ServiceBus.dll)
The CorrelationId is used for a faster way to apply filtering rules. For example, you could create a filter that would process all messages with a specific CorrelationId. The advantage of using the CorrelationId to SessionId is that CorrelationId is saved in a hash table, which speeds up the filtering process.
