NameDescription
System_CAPS_pubpropertyTransientWorkflow

Returns a cloned activity tree to which changes can be made and then applied to the running workflow instance.

Gets the condition property on a dependency object.

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

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

System_CAPS_pubmethodSystem_CAPS_staticSetCondition(Object, Object)

Sets the condition property on a dependency object.

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubmethodValidate()

Validates the current set of proposed changes that have been made to the activity tree represented by the TransientWorkflow property.

NameDescription

This material discusses types and namespaces that are obsolete. For more information, see Deprecated Types in Windows Workflow Foundation 4.5.

All proposed changes to a running workflow instance must be made using a WorkflowChanges object.

When a WorkflowChanges object is constructed in application code (outside the workflow instance), the Activity object that is passed to the constructor must be the object that is returned by the GetWorkflowDefinition method of the WorkflowInstance class.

The following example demonstrates creating a new instance of a WorkflowChanges object. This example is from the Ordering State Machine SDK sample. For more information, see Ordering State Machine Sample.

// Create a new instance of the WorkflowChanges class for managing
// the in-memory changes to the workflow
WorkflowChanges changes = new WorkflowChanges(root);
