QnA Maker can automatically create a Bot on Azure that links to the knowledge base you have. Recently, I was asked many times that the QnA Bot created by the template does not display the follow-up prompt. The follow-up prompt is just a PREVIEW feature of QnA Maker. The QnA Bot template has not supported this follow-up prompt feature yet. Before Microsoft Bot Framework officially supporting follow-up prompt feature, we have to make code change in order to support it in our QnA Bot. In this article, I will show you how to implement the follow-up prompt by changing the Bot code.
