Botbuilder 4.1.1
Classic task: we have waterfall dialog, in ctor i'm defining waterfall describing all steps:

var authenticate = new WaterfallStep
 
 AskForPhone,
 FinishOnboardingDialog,
 AskWhatToDo,
 AskTicketInfo
 ;

 AddDialog(new WaterfallDialog(InitialDialogId, authenticate));
 AddDialog(new TextPrompt("phonePrompt", CustomPromptValidatorAsync));
 AddDialog(new ChoicePrompt("optionsDialog"));
 AddDialog(new TextPrompt("askTicketInfo"));

...
then on one step i'm asking a prompt:

 public async Task<DialogTurnResult> FinishOnboardingDialog(WaterfallStepContext sc, CancellationToken cancellationToken)
 
 _state = await _accessor.GetAsync(sc.Context);

 return await sc.PromptAsync("optionsDialog", new PromptOptions()
 

 Choices = new List<Choice>()
 

 new Choice("Create a ticket"),
 new Choice("Contact your advisor organization"),
 new Choice("Contact AgriSync"),
 new Choice("List bot commands"),
 ,

 , cancellationToken);
 

Then on next step i'm checking the response.

On some of options i want just to collect info and go further. But on some option i would like to reprompt last question or go to some specific step of dialog.
In botbuilder v3 dialogs worked by old style callbacks, so every step was just a function and you could call it directly. Now as i get it you first define steps and their order, then on each step just call some prompts or await sc.NextAsync(), so when i'm trying to call steps like regular functions ( return await FinishOnboardingDialog(sc, cancellationToken); it worked but stack not flushed and i still get next step anyway.

Also i've succesfully used validation aproach, but it's kinda different case, this is good when actual validation happeing and if failed, step just keep reprompting.

Only aproach worked for me is

return await sc.ReplaceDialogAsync(InitialDialogId);

But i'm not sure i get whole idea of this named dialogs, not seems like much of documentation on this topic and no examples in c# in botbuilder-samples project regarding ReplaceDialogAsync.
Though it worked i would like to know if this is the correct way to do such loops and orchestrations and know more about this new named dialogs aproach. Thank you.
