Entities

Entities supporting workflows must implement ISupportsWorkflow interface, providing the required information as the interface contract oblige to. There is an additional requirement for workflow entities, which is to provide a parameterless constructor.

You create an entity by extending from BaseWorkflowStateMachineInstance class, which provides the properties required by workflow entities, as the example shows here below:

public class ServiceOrder : BaseWorkflowStateMachineInstance
{
    public ServiceOrder()
    {
    }

    public ServiceOrder(Guid correlationId)
    {
        this.CorrelationId = correlationId;
    }
}

Note

Bear in mind that by extending from BaseWorkflowStateMachineInstance, which implements

ISupportsWorkflow, the framework will be mapping the interface contract properties to EntityFramework for you.
