In this example, a workflow is created that consists of a single WriteLine activity. The WriteLine activity has an InArgument(Of T) named Text. The host application creates an instance of the workflow and passes a string, which maps to the Text argument of the WriteLine and is used by the WriteLine activity.

C#
Copy 
Activity wf = new WriteLine();

Dictionary<string, object> wfParams = new Dictionary<string, object>();
wfParams.Add("Text", "Hello World!");

WorkflowInvoker.Invoke(wf, wfParams);
