Support QnAMaker Follow-up Prompts

The QNA portal implemented a new feature to allowusers to define follow-up questions, those follow-up questions are returned in a ‘context’ property in the service response, but the QnAMaker.GetAnswersAsync method doesn´t return that property (only the answer)…

Solution The Bot Framework should auntomatically generate/present dynamic cards when a QNA answer includes follow-up questions.

I am using bot version 4.5.1, are the prompts available? or do I need to create the context manually? I do not see “context”: { “isContextOnly”: false, “prompts”: [ { “displayOrder”: 0, “qnaId”: 182, “qna”: null, “displayText”: “what type of assistant?” } ] } in intellisense.

Is there an up to date version of this sample? https://github.com/microsoft/BotBuilder-Samples/tree/master/experimental/qnamaker-prompting/csharp_dotnetcore
