How to pass the data like domain model to custom workflow clas inherited from WorkflowBase,

[hunter3UA]

Hello. Have a question regarding WorkflowBase class
How can I pass my domain model to workflow classes?

Declare the model as a workflow input, then retrieve it from the execution context inside the activity graph. For example:

public sealed class MyWorkflow : WorkflowBase
{
    protected override void Build(IWorkflowBuilder builder)
    {
        var order = builder.WithInput<Order>("Order");
        builder.Root = new Sequence
        {
            Activities =
            {
                new WriteLine(context => context.GetInput<Order>(order).Id.ToString())
            }
        };
    }
}

Start the workflow with an input dictionary containing "Order" and the domain-model value. The code-first tests use the same pattern with builder.WithInput<T>(...) and context.GetInput<T>(...).

Relevant examples:

• Elsa.Workflows.ComponentTests/.../ChildWorkflowWithInput.cs
• Elsa.Workflows.IntegrationTests/.../GreeterWorkflow.cs

If the model crosses a persistence or distributed-dispatch boundary, make sure it is serializable by the serializer configured for your host.
