The document outlines various programming languages and tools used in developing computer applications and chatbots, highlighting the evolution of machine language for better human-computer interaction. It discusses the features and improvements made in bot frameworks, including their flexibility and modularity, as well as middleware events for handling messages and conversation updates. Additionally, it includes references to resources for bot development and the use of AI for enhancing user experiences.

- 2. Expression Spectrum Machine Language C, C++ C#, Java, JavaScript, PHP, Perl Graphical User Interface Natural Language • Computers need to be told what to do – exactly and unambiguously. • Ever since Grace Hopper, computer scientists have been working to make it easier for humans to express their intentions to computers. Shell scripts, PowerShell Power Platform, Excel RAD tools COBOL

- 5. BotBuilder v3 BotBuilder v4 C#, Node.js Inconsistent naming Monolithic and opinionated Complex dependency trees Opinionated C#, JavaScript, Python, Java Incorporates feedback from v3 Less “opinionated”, more flexible Modular and Extensible Not backward compatible

- 9. Testing your Bot App Service with Remote Debugger Run directly in Azure Attach Visual Studio debugger Bot Framework Emulator Separate download Does not require registration Can connect to bot on localhost Supports speech recognition Send sample Team Member Events ngrok Tunnel Tunnels internet requests to local machine Allows inspection of request/response Free version changes the URL every time you use it (8 hr max/use)
- 10. Middleware
- 11. Event (C#, JavaScript) Fires when Description OnTurnAsync, onTurn Any activity is received Base class calls the other handlers – if you override w/o calling base.OnTurnAsync(), no further processing will happen! OnMessageActivityAsync, onMessage A message is received Override to handle message activities OnConversationUpdateActivi tyAsync, onConversationUpdate A conversation update is received Eg/ someone enters or leaves the conversation OnInvokeAsync, onInvoke An Invoke activity is received Used heavily in Teams for message extensions, adaptive cards

Editor's Notes
- #7: Activities are more than receiving messages, and include Typing (user is typing) and ConversationUpdate (members added and removed from the conversation). Text messages are always possible, but beyond that message formats vary by application; Bot needs to deal with that.
- #9: Explain that setup is in the notes; show templates Crank up the NodeJS echobot in the emulator; explain Show Bot service registration Show Teams manifest Show bot in Teams
