问题：模拟器中显示的欢迎消息，但在我输入任何内容后仅显示发布后，在WebChat Bot中不显示？应在浏览器中打开WebChatbot后立即显示欢迎消息。
语言：c＃
bot sdk：v4
bot Builder软件包：全部最新直到4.4.3通过Nuget
bot仿真器：最新的4.4.1从github发行
下载并安装在ibot类的Onturnsync方法中，欢迎文本在对话update活动中被调用。下面给出的代码供参考。
请提供帮助，因为我是刚刚进行机器人和编码，通过提供逐步指导？
我已经尝试了一些事情：
- 模拟器中的调试但没有帮助
我使用过的代码下方：
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：不仅在模拟器中发布后，还应在WebChatbot中显示欢迎文本。
实际结果：仅在模拟器中工作，但在WebChatbot中不工作，仅在我输入任何内容后才显示。
这是关于欢迎用户的常见问题。
在每个频道上抛出的事件并不相同：Webchat和Emulator中事件之间的主要区别之一是：
- 在模拟器上，在对话的开头发送了2个
ConversationUpdate事件(添加了1个，其中1个用户添加了1个( - 在网络聊天上，仅在用户发送1个消息 之后发送有关用户的
ConversationUpdate因此，要绕过此行为，您可以使用称为backchannel的机制在侧面处理event。在GitHub的存储库上，此用例有一个样本
用几句话，您必须：
- 从start 发送网络聊天的事件
- 在机器人侧处理此事件，然后您欢迎消息
