BOT Framework 模拟器停止呈现 HTML

BOT Framework emulator stopped rendering HTML

Bot Framework 突然停止渲染html,我附上截图。有什么问题?我正在使用最新的 v3.5.31。我使用了创建新 BOT 项目时默认可用的 Bot 应用程序模板。

下面是我写的代码

[Serializable]
    public class RootDialog : IDialog<object>
    {
        public Task StartAsync(IDialogContext context)
        {
            context.Wait(MessageReceivedAsync);

            return Task.CompletedTask;
        }

        private async Task MessageReceivedAsync(IDialogContext context, IAwaitable<object> result)
        {
            PromptDialog.Text(context, resumeAfter, "Enter your name", "Didn't get that",
                      3
                      );
        }

        private async Task resumeAfter(IDialogContext context, IAwaitable<string> result)
        {
            string answer = await result;
            await context.PostAsync($"Hello <i><b>{answer}</b></i>");
        }
    }

已报告here. and it looks like it's by design in the WebChat control (that is what the Emulator uses behind the scenes). See the change in the WebChat control: https://github.com/Microsoft/BotFramework-WebChat/commit/a5cd8cffb7a97fb925e4078dbe1085694fa92f80
