Problems with choice prompt

Not sure how to use choiceprompt 

    private async Task<DialogTurnResult> PromptForRequestStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
            return await stepContext.PromptAsync(
    RequestPrompt,
    new PromptOptions
    {
        Prompt = MessageFactory.Text("Please choose a location."),
        RetryPrompt = MessageFactory.Text("Sorry, please choose a location from the list."),
        Choices = ChoiceFactory.ToChoices(new List<string> { "1", "2", "3" }),
    });
        }

    private async Task<DialogTurnResult> PromptForTutorialStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        // Save name, if prompted.
        var context = stepContext.Context;
        var location = stepContext.Result;
        var greetingState = await UserProfileAccessor.GetAsync(context);
        greetingState.Request = stepContext.Result as string;

        await UserProfileAccessor.SetAsync(stepContext.Context, greetingState);

        if (greetingState.Request == "1")
        {
            var opts = new PromptOptions
            {
                Prompt = new Activity
                {
                    Type = ActivityTypes.Message,
                    Text = $"1- Login to OneDrive" + Environment.NewLine + "2- Upload a file" + Environment.NewLine + "3- Create a folder",
                },
            };
            return await stepContext.PromptAsync(OneDrivePrompt, opts);
        }

When I run the bot. The options show up and I can press the button with "1" to input 1. I am not sure how to make the next step of the waterfallstep work with the choiceprompt I used. The code worked when i was doing a simple textprompt. I changed it to choiceprompt and it does not work. What do I need to do to make it work?

I assume you're saying that the prompt with the id value in your RequestPrompt variable is defined as a ChoicePrompt?

If so a ChoicePrompt's result will be a FoundChoice instance. So, assuming the step that follows that prompt is the PromptForTutorialStepAsync you show here, you would cast the result to a FoundChoice and then use that API to access the actual value.

The simplest, though arguable not the most legible, way would be as follows:

var location = ((FoundChoice)stepContext.Result).Value;

Do you have a repository to look at to see the difference between working and broken?

From the current glance, here are a couple of things to check: 1) The "return await stepContext.PromptAsync(OneDrivePrompt, opts);" looks like an unnecessary await. Let the Task class do it's work.

2) Do you know at which line the program stops?
