This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.
If a TrackingService is present, the runtime tracking infrastructure calls GetTrackingChannel to get a tracking channel for a workflow instance. The runtime tracking infrastructure uses this tracking channel to send tracking records associated with the workflow instance back to the host application whenever the tracking infrastructure matches a track point in the TrackingProfile associated with the workflow instance. Your application can treat this tracking information in any way you choose. For example, the SqlTrackingService writes tracking information to a SQL database.
To create a tracking channel for your tracking service, derive a class from the TrackingChannel base class. You can use the TrackingParameters object passed by the runtime tracking infrastructure in its call to your implementation of GetTrackingChannel to associate each instance of your tracking channel with a specific workflow instance. The workflow runtime engine requests a tracking channel from each tracking service that has provided a TrackingProfile for a workflow instance.
