Initializes a new instance of the WorkflowIdentity class.

System_CAPS_pubmethodWorkflowIdentity(String, Version, String)

Initializes a new instance of the WorkflowIdentity class using the name, version, and package.


Gets or sets the name of the workflow identity.


Gets or sets the package of the workflow identity.


Gets or sets the version of the workflow identity.


Determines whether the specified object is equal to the current object.(Overrides Object.Equals(Object).)


Determines whether the current WorkflowIdentity and the specified WorkflowIdentity are the same.


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Returns the hash code for this workflow identity.(Overrides Object.GetHashCode().)


Gets the Type of the current instance.(Inherited from Object.)

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.
