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 more information about disabling validation, see ValidateOnCreate.
For an example of passing in parameters to CreateWorkflow, see Workflow with Parameters Sample.
