.NET : Subworkflow Output behavior

[jmurkothintel]

Scenario
Have a workflow with a starting edge that is an agent , this edge then invokes another edge that is actually a subworkflow. This subworkflow is a concurrent workflow with multiple agents set up using the AgentWorkflowBuilder.BuildConcurrent method.

Observation
When the sub workflow is set up as the output for the WithOutputFrom method, the WorkflowOutputEvent was not being fired. As a work around added another executor edge and set it to be the output in WithOutputFrom and things started working as shown below

AIAgent essayAgent = new EssayAgent(configuration).Agent; // Agent writes an essay on a topic

// Step 2: Configure the sub-workflow as an executor for use in the parent workflow . This translates the essay
ExecutorBinding subWorkflowExecutor = translatorWorkFlow.BindAsExecutor("TranslatorWorkflow"); // There are 3 agents in this concurrent workflow

PostProcessExecutor postProcessExecutor = new PostProcessExecutor(); // executor added to get it to work

var workflow = new WorkflowBuilder(essayAgent)
    .AddEdge(essayAgent, subWorkflowExecutor)
    .AddEdge(subWorkflowExecutor,postProcessExecutor)
    .WithOutputFrom(postProcessExecutor)
    .Build();

Expectation
Ideally would expect the WorkflowOutputEvent event to fire when the subworkflow as completed . Nevertheless Would like to understand the expected behavior in this case , if this is a bug or the expected behavior and we have to have a final edge added after a sub workflow invocation

@alliscode This is the issue that I was referencing in the office hours yesterday

@lokitoth could you take a look at this one when you have time.
