IDiagnosticSourceActivityFilter.TryGetCorrelationKey Method
TryGetCorrelationKey(Object, out Object)
Method called by DiagnosticSourceCollectingListener when a message suffixed .Start or .Stop is captured. The implementation
must return the correlation object, i.e. a property of the message that is identical for both the start and the stop messages. This correlation key
allows to pair the messages as a single activity. When the implementation returns null, no activity is created.
