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.
