我使用 SDK 4 在 C# 中创建了聊天机器人，当用户在浏览器中打开网络聊天机器人时，我尝试显示欢迎文本。
目前，欢迎文本显示在模拟器中，但在发布到 Azure 后打开的 WebchatBot 离子浏览器中不显示。
仅在我输入“嗨”或其他内容后，它才显示欢迎消息。情况不应该是这样，它应该首先显示欢迎文本，然后我可以输入 Hi 或其他任何内容来继续对话
问题：发布后，欢迎消息显示在模拟器中，但不显示在网络聊天机器人中，仅在我输入任何内容后才显示？在浏览器中打开 Webchatbot 后应立即显示欢迎消息。
语言：C#
机器人 SDK：V4
Bot Builder 软件包：全部通过 Nuget 更新至 4.4.3
Bot Emulator：从 GitHub 版本下载并安装最新的 4.4.1
欢迎文本在 IBOT 类的 OnTurnSync 方法内的 ConversationUpdate 活动中调用。下面给出代码供参考。
由于我是 BOT 和编码的新手，请提供逐步指导来帮助我？
我已经尝试过一些事情，例如：
- 在模拟器中调试
但没有多大帮助
我使用过以下代码：
public const string WelcomeText = "Welcome!. This bot uses a custom dialog that executes a data driven flow. Type anything to get started.";
public async Task OnTurnAsync(ITurnContext turnContext, CancellationToken cancellationToken = default(CancellationToken))
{
if (turnContext.Activity.Type == ActivityTypes.ConversationUpdate)
{
if (turnContext.Activity.MembersAdded != null)
{
await SendWelcomeMessageAsync(turnContext, cancellationToken);
}
}
}
private static async Task SendWelcomeMessageAsync(ITurnContext turnContext, CancellationToken cancellationToken)
{
foreach (var member in turnContext.Activity.MembersAdded)
{
if (member.Id != turnContext.Activity.Recipient.Id)
{
var reply = turnContext.Activity.CreateReply();
reply.Text = WelcomeText;
await turnContext.SendActivityAsync(reply, cancellationToken);
}
}
}
预期结果：欢迎文本不仅在模拟器中发布，还应在发布后显示在 WebchatBot 中。
实际结果：欢迎文本仅在模拟器中有效，但在网络聊天机器人中无效，只有在我输入任何内容后才会显示。
