Tracking Service Attribute Class
This API is now obsolete.
Indicates the type of the TrackingService that was used prior to the current version.

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.
When an assembly containing a new version of a TrackingService implementation is deployed, this attribute is applied to the new version of the tracking service class to identify the assembly of the previous version. This allows the runtime to utilize the newer tracking service for workflows that were using persisted while using the previous version of the tracking service, but resumed after the new version was implemented.
Creates a new instance of the PreviousTrackingServiceAttribute class.
Gets the fully qualified assembly name of the previous version tracking service that this version replaces.
When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute)
Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute)
Returns the hash code for this instance.(Inherited from Attribute)
Gets the Type of the current instance.(Inherited from Object)
When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute)
When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute)
Creates a shallow copy of the current Object.(Inherited from Object)
Returns a string that represents the current object.(Inherited from Object)
