feat: add multiple messages pattern to dotnet agent-framework sample by sellakumaran · Pull Request #246 · microsoft/Agent365-Samples

sellakumaran · 2026-03-12T23:39:05Z

Demonstrates the recommended pattern for sending multiple discrete messages to a Teams user from a single agent turn:

Immediate ack via SendActivityAsync before LLM processing
Typing indicator loop (refreshed every 4s, properly awaited in finally)
StreamingResponse retained as best-effort for non-Teams/WebChat clients

Documents the pattern in README with code examples and notes on typing indicator limitations (1:1 and small group chats only, ~5s timeout).

- Add ArgumentNullException guard for turnContext before InvokeObservedAgentOperation - Expand empty OperationCanceledException catch block with explanatory comment Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

…) across all dotnet and nodejs samples Implements issue #268 pattern — send an immediate ack message, run a typing indicator loop every ~4s, then deliver the LLM response as a second discrete message. All changes include README documentation. dotnet/semantic-kernel: - Send ack + single typing indicator in MessageActivityAsync before GetAgent365Agent so they arrive before the streaming connection opens - Read OboAuthHandlerName from config (was hardcoded) - Register InstallationUpdate for both agentic and non-agentic identities - Add SKIP_TOOLING_ON_ERRORS to launchSettings for local dev nodejs (openai, langchain, langchain/quickstart-before, claude, vercel-sdk, devin, perplexity, copilot-studio): - Add ack sendActivity before LLM call - Add setInterval typing loop (~4s); stopped in finally block - Add/fix InstallationUpdate handler where missing (copilot-studio, quickstart-before) nodejs/langchain/quickstart-before (additional pre-existing fixes): - Fix build errors: instructions → systemPrompt (langchain 1.2.32 API change) - Add @types/express and @types/node devDependencies - Add Azure OpenAI support alongside standard OpenAI in client.ts Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Python (openai, claude, crewai, google-adk, agent-framework): add immediate ack message ("Got it — working on it…"), explicit typing indicator await before create_task, and asyncio background loop refreshing every 4s - Node.js (openai, claude, langchain, vercel-sdk, copilot-studio): remove startTypingTimer: true (fires before ack, wrong order) and add explicit await sendActivity(typing) after ack, before setInterval loop - dotnet agent-framework: add explicit typing await on main thread before Task.Run, fix loop order (Delay first then send), move null guard to top of OnMessageAsync (fixes Copilot review finding) - crewai: fix pysqlite3-binary to Linux-only (no Windows wheel), add Azure LLM config (azure/gpt-4o) to agents.yaml - All Python READMEs: add "Sending Multiple Messages in Teams" section with correct code example including explicit typing line Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Pull request overview

Adds a consistent “multiple discrete messages per turn” UX pattern across the Agent365 sample agents (ack → typing → final response), and documents the approach/limitations for Teams clients.

Changes:

Updated Python and Node.js sample message handlers to send an immediate ack and keep a typing indicator alive during LLM work.
Updated .NET agent-framework and semantic-kernel samples to document (and in agent-framework, implement) multi-message + typing patterns.
Added cross-sample tracking doc and a few sample maintenance tweaks (CrewAI config, platform-specific dependency condition, quickstart fixes, env/launch settings).

…t, copyright headers, ordering - Node.js (8 files): replace setInterval(async () => await sendActivity) with non-async callback + .catch() to prevent unhandled Promise rejections if sendActivity fails - Python (4 files): add explanatory comment to empty except asyncio.CancelledError blocks - Python (3 files): normalize copyright header from 'Microsoft.
