To Reproduce

Steps to reproduce the behavior: Run the code in Visual Studio. using EchoBot.Services; using Microsoft.Bot.Builder.Dialogs; using System; using System.Text.RegularExpressions; using System.Threading; using System.Threading.Tasks;

namespace EchoBot.Dialogs { public class MainDialog : ComponentDialog { private readonly StateService _stateService;

    public MainDialog(StateService stateService) : base(nameof(MainDialog))
    {
        _stateService = stateService ?? throw new ArgumentNullException(nameof(stateService));

        InitializeWaterfallDialog();
    }

    private void InitializeWaterfallDialog()
    {
        var waterfallSteps = new WaterfallStep[]
        {
            InitialStepAsync,
            FinalStepAsync
        };
        //Add named dialogs
        AddDialog(new GreetingDialog($"{nameof(MainDialog)}.greeting", _stateService));
        AddDialog(new BugReportDialog($"{nameof(MainDialog)}.bug", _stateService));

        AddDialog(new WaterfallDialog($"{nameof(MainDialog)}.mainFlow", waterfallSteps));

        //Set the starting dialog
        InitialDialogId = $"{nameof(WaterfallDialog)}.mainFlow";
    }
    private async Task<DialogTurnResult> InitialStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        if (Regex.IsMatch(stepContext.Context.Activity.Text.ToLower(), "hi"))
        {
            return await stepContext.BeginDialogAsync($"{nameof(MainDialog)}.greeting", null, cancellationToken);
        }
        else
        {
            return await stepContext.BeginDialogAsync($"{nameof(MainDialog)}.bug", null, cancellationToken);
        }
    }

    private async Task<DialogTurnResult> FinalStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        return await stepContext.EndDialogAsync(cancellationToken);
    }

}
