Bot框架412當連接Luis時「數據發生變化」

我在Luis的幫助下有一個簡單的機器人。這是非常基本的代碼，我不知道爲什麼我在向Luis意圖傳遞消息之後得到了412錯誤。我的代碼如下所示：Bot框架412當連接Luis時「數據發生變化」

MessageController：

if (activity.Type == ActivityTypes.Message) 
{ 
    // Get any saved values 
    StateClient sc = activity.GetStateClient(); 
    await sc.BotState.GetUserDataAsync(activity.ChannelId,activity.From.Id); 

    var haveGreeting = userData.GetProperty<bool>("HaveGreeting"); 
    // Create text for a reply message 
    StringBuilder strReplyMessage = new StringBuilder(); 
    if (haveGreeting == false) 
    { 
     strReplyMessage.Append($"Hi, how are you today?"); 
     userData.SetProperty("HaveGreeting", true); 
    } 
    else 
    { 
     await Conversation.SendAsync(activity,() => new MeBotLuisDialog()); 
    } 

    // Save BotUserData 
    var botaData = await sc.BotState.SetUserDataAsync(activity.ChannelId, 
     activity.From.Id, userData); 
    // Create a reply message 
    ConnectorClient connector = new ConnectorClient(new Uri(activity.ServiceUrl)); 
    Activity replyMessage = activity.CreateReply(strReplyMessage.ToString()); 
    await connector.Conversations.ReplyToActivityAsync(replyMessage); 
}

路易斯意圖：

[LuisIntent("HowAreYou")] 
public async Task HowAreYou(IDialogContext context, IAwaitable<IMessageActivity> activity, LuisResult result) 
{ 
    await context.PostAsync("Great! Thank for asking"); 
    context.Wait(MessageReceived); 
}

請幫幫忙！

這是否在模擬器失敗？ –

不，我已經發布此測試機器人，但仍然得到此問題 –

請參閱http://stackoverflow.com/questions/42860020/microsoft-bot-framework-exception-the-data-is-changed/42913460#42913460 – Artem

嘗試在Global.asax.cs文件中添加以下代碼

var builder = new ContainerBuilder(); 
builder 
    .Register(c => new CachingBotDataStore(c.Resolve<ConnectorStore>(), CachingBotDataStoreConsistencyPolicy.LastWriteWins)) 
    .As<IBotDataStore<BotData>>() 
    .AsSelf() 
    .InstancePerLifetimeScope(); 
builder.Update(Conversation.Container);
