Even if you've never heard of adaptive cards, you've probably used them in applications like Microsoft Outlook, Teams, and Windows 10. Developers can use adaptive cards to build snippets of UI that are rendered natively inside of another application. In this session you'll learn how to create your own adaptive cards, send them to Microsoft Teams, and respond to actions when users interact with the card. You'll even learn how to host adaptive cards in a web page. Join in for a quick intro to this new open-source UI tool set!
