I am using Visual studio 2017 with Bot framework 3.8.1. Created simple QnA Maker dialog using with cognitive services 1.1.0. QnA maker is working fine, I have tested it online. However when I test the bot which triggers QnA maker I get following exception :

Exception: Method not found: 'Void Microsoft.Bot.Builder.Dialogs.PromptOptions1..ctor(System.String, System.String, System.String, System.Collections.Generic.IReadOnlyList1, Int32, Microsoft.Bot.Builder.Dialogs.PromptStyler, System.Collections.Generic.IReadOnlyList`1)'.",

This works well when I develop using Visual Studio 2015.

What could be the issue?

This is known issue due to the latest updates done on BotBuilder SDK. It was reported here. To unblock yourself you can just re-compile the library using the latest version of BotBuilder, that will make the trick.
