I am trying to write a simple bot that uses LUIS, but seem to have an issue with after an update. 

So before updating the Botbuilder to 1.1, I was having issues where Luis.Models couldn't be found. After the upgrade, and resolving a [coding error](https://stackoverflow.com/questions/37695677/attribute-luismodel-is-not-valid-on-this-declaration-type), and removing Microsoft.Bot.Connector.Utilities, I can compile and run successfully, but I can't connect via the emulator. 

This is the code I am using.

```
using System;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Threading.Tasks;
using System.Web.Http;
using System.Web.Http.Description;
using System.Collections.Generic;
using Microsoft.Bot.Connector;
using Microsoft.Bot.Builder.Dialogs;
//using Microsoft.Bot.Connector.Utilities;
using Microsoft.Bot.Builder.Luis;
using Microsoft.Bot.Builder.Luis.Models;
using Newtonsoft.Json;

[LuisModel("c413b2ef-382c-45bd-8ff0-f76d60e2a821", "6d0966209c6e4f6b835ce34492f3e6d9")]
[Serializable]
public class Mybot : LuisDialog<object>
{

    [LuisIntent("")]
    public async Task None(IDialogContext context, LuisResult result)
    {
        string message = "I'm sorry I didn't understand. Try asking about your bill.";
        await context.PostAsync(message);
        context.Wait(MessageReceived);
    }

    [LuisIntent("NextInvoiceDate")]
    public async Task NextInvoiceDate(IDialogContext context, LuisResult result)
    {
        string message = "Your next payment will go out on the 17th of the month.";
        await context.PostAsync(message);
        context.Wait(MessageReceived);
    }

    [LuisIntent("NextAmount")]
    public async Task NextAmount(IDialogContext context, LuisResult result)
    {
        string message = $"Your next amount is expected to be around £29.72.";
        await context.PostAsync(message);
        context.Wait(MessageReceived);
    }
}

```

When I run the project, it starts without errors, and I get the webpage that says:

*MYBot
Describe your bot here and your terms of use etc.
Visit Bot Framework to register your bot. When you register it, remember to set your bot's endpoint to 
<https://your_bots_hostname/api/messages>*

When I run the emulator pointing to <https://localhost/api/messages>, it retuns "an error occurred while sending the request". 

The JSON is here:

```
System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:443

   at Microsoft.Bot.Connector.Emulator.ConversationModel.<SendMessageAsync>d__50.MoveNext() 

```

I have also tried just HTTP (rather than HTTPS).
