	Type workflowType,
	Dictionary<string, Object> namedArgumentValues

A Dictionary<TKey, TValue> of objects keyed by string that represents the arguments to the workflow.

Return Value

Type: System.Workflow.Runtime.WorkflowInstance
A WorkflowInstance object that represents the workflow instance created.


workflowType is a null reference (Nothing in Visual Basic).

Before the WorkflowInstance is created, validation is executed on it. If any validation errors occur, the WorkflowValidationFailedException is thrown. This works well for simple scenarios, but in a server environment, revalidating a workflow for every activation might be unnecessary overhead.

For information about disabling validation, see ValidateOnCreate.

For an example of passing in parameters to CreateWorkflow, see Workflow with Parameters Sample.
