title: Microsoft Bot Framework - Adaptive card version not supported in Teams and Skype for Business
body: <p>I have created a bot and deployed it to Azure. In the Azure portal, I have configured Skype for business and Microsoft Teams as channels for my bot.
  The bot is using Adaptive Cards to show details of entities, the user has entered (to create a meeting).</p>
  
  <p>I have tested the bot with Bot Framework Emulator using the Azure URL of the bot. Everyting works as expected.
  - Entities are properly resolved with LUIS
  - Details are filled in the Adaptive Card
  - The Adaptive Card is showing in the chat window.</p>
  
  <p>Not so for Skype for Business and Microsoft Teams.
  Nothing at all is showing in Skype for Business.</p>
  
  <p>In Microsoft Teams, I receive an error message "The specified card version is not supported.".
  I am using the latest NuGet Packages for BotBuilder - Version 3.16 at this point of time. Anyway, the problem exists.</p>
  
  <p>I'd expect, Adaptive Cards code would be compatible with all Microsoft products.
  What can I do, to get my Adaptive Cards working in Teams, Skype for Business... ?</p>
