Maps a persisted workflow instance to its corresponding workflow definition.

System.Object
System.Activities.WorkflowIdentity

Namespace: System.Activities
Assembly: System.Activities (in System.Activities.dll)

[<SerializableAttribute>]
[<TypeConverterAttribute(typeof(WorkflowIdentityConverter))>]
[<DataContractAttribute>]

Remarks

This class supports the versioning and dynamic update functionality of Windows Workflow Foundation. For more information about workflow versioning, workflow identity, and dynamic update, see the following topics.

Workflow Versioning: Describes the workflow versioning functionality introduced in .NET Framework 4.5.
Dynamic Update: Describes how to update the workflow definition of a persisted workflow instance by using dynamic update.
Using WorkflowApplication Identity and Versioning: Describes how to use WorkflowIdentity to host multiple versions of a workflow side-by-side.
Side by Side Versioning in WorkflowServiceHost: Describes how to host multiple versions of a workflow on a single endpoint.
How to: Host Multiple Versions of a Workflow Side-by-Side: This step in the Getting Started Tutorial demonstrates updating a workflow definition, and hosting workflows using both the old and new definition at the same time.
How to: Update the Definition of a Running Workflow Instance: This step in the Getting Started Tutorial demonstrates updating persisted workflow instances to use a new workflow definition.
