System.Workflow.Runtime.Tracking Namespace

Contains classes and an interface related to tracking services.

Tracking services are used to define tracking information that you want a workflow instance to emit during its execution and to provide a tracking channel on which the workflow instance can send this specified information back to the host application. Tracking services can be optionally added to the workflow runtime engine; unlike some of the other core services, a tracking service is not required by the workflow runtime engine. You can use the classes and interface defined in the System.Workflow.Runtime.Tracking namespace to either implement a custom tracking service, or to use the out-of-box SQL tracking service.

  ClassDescription
Public classActivityDataTrackingExtractSpecifies a property or a field to be extracted from an activity and sent to the tracking service together with an associated collection of annotations when a track point is matched.
Public classActivityTrackingConditionRepresents a condition that compares the value of an activity member to a specified value by using a specified comparison operator.
Public classActivityTrackingLocationDefines an activity-qualified location that corresponds to an activity status event in the potential execution path of a root workflow instance. This class cannot be inherited.
Public classActivityTrackingLocationCollectionContains a collection of ActivityTrackingLocation objects.
Public classActivityTrackingRecordContains the data sent to a tracking service by the runtime tracking infrastructure when an ActivityTrackPoint is matched. It is also used in the return list of the ActivityEvents property.
Public classActivityTrackPointDefines a point, associated with an activity execution status change, to be tracked that is in the potential execution path of a workflow instance. This class cannot be inherited.
Public classActivityTrackPointCollectionContains a collection of ActivityTrackPoint objects.
Public classExtractCollectionContains a collection of TrackingExtract objects.
Public classPreviousTrackingServiceAttributeIndicates the type of the TrackingService that was used prior to the current version.
Public classProfileRemovedEventArgsProvides data for the ProfileRemoved event. This class cannot be inherited.
Public classProfileUpdatedEventArgsProvides the data for the ProfileUpdated event. This class cannot be inherited.
Public classSqlTrackingQueryContains methods and properties that are used to manage queries to the tracking data that is contained in the SQL database used by a SqlTrackingService.
Public classSqlTrackingQueryOptionsContains properties that are used to constrain the set of SqlTrackingWorkflowInstance objects returned by a call to SqlTrackingQuery.GetWorkflows.
Public classSqlTrackingServiceRepresents a tracking service that uses a SQL database to store tracking information.
Public classSqlTrackingWorkflowInstanceProvides access to tracking data maintained in a SQL database by the SqlTrackingService for a workflow instance.
Public classTrackingAnnotationCollectionContains a collection of annotations.
Public classTrackingChannelThe abstract base class that represents a tracking channel.
Public classTrackingConditionAn abstract base class representing a comparison that can be used to constrain an ActivityTrackingLocation or a UserTrackingLocation.
Public classTrackingConditionCollectionContains a collection of TrackingCondition objects.
Public classTrackingDataItemRepresents a single item of data extracted from a workflow and all its associated annotations.
Public classTrackingDataItemValueContains filter criteria for data extracted from a workflow instance in a SqlTrackingQueryOptions.
Public classTrackingExtractThe abstract base class representing a field or a property to be extracted from a workflow instance and its associated annotations.
Public classTrackingParametersContains information about the workflow instance associated with a TrackingChannel. This class cannot be inherited.
Public classTrackingProfileDefines points of interest in the potential execution path of a root workflow instance about which a tracking service should be notified.
Public classTrackingProfileCacheProvides a method that a host application can use to clear the tracking profile cache.
Public classTrackingProfileDeserializationExceptionThe exception that is thrown when an XML document cannot be deserialized into a TrackingProfile by a TrackingProfileSerializer.
Public classTrackingProfileSerializerProvides methods to serialize and deserialize tracking profiles into and from XML documents by using the tracking profile XML schema definition (XSD).
Public classTrackingRecordThe abstract base class from which ActivityTrackingRecord, UserTrackingRecord, and WorkflowTrackingRecord are derived.
Public classTrackingServiceThe abstract base class that provides the basic interface between a tracking service and the run-time tracking infrastructure.
Public classTrackingWorkflowChangedEventArgsContains data associated with a workflow change that occurs during the execution of a workflow instance.
Public classTrackingWorkflowExceptionEventArgsContains data associated with an exception that occurs during the execution of a workflow instance.
Public classTrackingWorkflowSuspendedEventArgsContains information about the reason that a workflow instance was suspended.
Public classTrackingWorkflowTerminatedEventArgsContains data associated with the termination of a workflow instance.
Public classUserTrackingLocationDefines an activity-qualified location that corresponds to a user event in the potential execution path of a root workflow instance. This class cannot be inherited.
Public classUserTrackingLocationCollectionContains a collection of UserTrackingLocation objects.
Public classUserTrackingRecordContains the data sent to a tracking service by the runtime tracking infrastructure when a UserTrackPoint is matched.
Public classUserTrackPointDefines a point, associated with a user event, to be tracked in the potential execution path of a root workflow instance. This class cannot be inherited.
Public classUserTrackPointCollectionContains a collection of UserTrackPoint objects.
Public classWorkflowDataTrackingExtractSpecifies a property or a field to be extracted from the root activity of the workflow and sent to the tracking service together with and an associated collection of annotations when a track point is matched.
Public classWorkflowTrackingLocationDefines an interest in specific workflow status events that occur in a root workflow instance; used for matching by a WorkflowTrackPoint in a tracking profile. This class cannot be inherited.
Public classWorkflowTrackingRecordContains the data sent to the tracking service by the runtime tracking infrastructure when it matches a WorkflowTrackPoint. It is also used in the return list of the WorkflowEvents property.
Public classWorkflowTrackPointDefines a point associated with a set of workflow status events that are tracked in the potential execution path of a root workflow instance.
Public classWorkflowTrackPointCollectionContains a collection of WorkflowTrackPoint objects.

  InterfaceDescription
Public interfaceIProfileNotificationProvides a notification mechanism for a tracking service to inform the runtime tracking infrastructure about changes to the TrackingProfile for a particular workflow Type.

  EnumerationDescription
Public enumerationComparisonOperatorSpecifies the operation to perform on the operands of a comparison.
Public enumerationTrackingWorkflowEventSpecifies a type of workflow status event.
