Must be overridden in the derived class, and when implemented, retrieves a new tracking profile for the specified workflow instance if the tracking profile has changed since it was last loaded.

- profile
- TrackingProfile
When this method returns, contains the TrackingProfile to load. This parameter is passed uninitialized.
Returns
true if a new TrackingProfile should be loaded; otherwise, false. If true, the TrackingProfile is returned in profile.
Remarks
TryReloadProfile is called by the run-time tracking infrastructure to determine whether a new TrackingProfile should be loaded for the specified workflow instance. If a new TrackingProfile is required, it is returned in profile. If you want the run-time tracking infrastructure to stop tracking a workflow instance, your tracking service should return true and set profile equal to a null reference (Nothing in Visual Basic). Your tracking service can use workflowType or workflowInstanceId in whatever manner you choose to determine whether a tracking profile should be reloaded. For example, the SqlTrackingService only uses workflowInstanceId to decide whether the tracking profile should be reloaded. TryReloadProfile is called by the run-time tracking infrastructure according to its own tracking semantics, or in response to the host or a service calling WorkflowInstance.ReloadTrackingProfiles on a workflow instance.
