i simply created a wcf service which is printing "hello world". created a sequential console workflow, added a send activity and code activity to the workflow. referenced the service here. configured the send activity. created dependency property for return value.
now when I am running the app. it throws a format exception in program.cs file on the line
WorkflowInstance instance = workflowRuntime.CreateWorkflow(typeof(Using_SendActivity.Workflow1));
Where have I gone wrong?
System.FormatException was unhandled
Message="Input string was not in a correct format."
