June 2025 Monthly Summary (microsoft/teams.net, microsoft/teams.ts) Key features delivered and major improvements: - Streaming Informational Updates: Added Update method on Streamer and a new StreamType for informational messages (e.g., Thinking...). This enables proactive status signaling during streaming sessions and improves user feedback during long-running streams. Commit: 185025e68ed543257f47f4caa422189ddb377af6 (Add support for informative updates (#60)). - BotBuilder Plugin for AspNetCore: Introduced a new BotBuilder plugin package, updated TeamsSettings for credentials, and added a MessageController to manage bot messages, expanding teams bot capabilities in ASP.NET Core apps. Commit: dda763b06eab9465a0c5c4edc25e67758b601830 (Adds BotBuilder plugin package (#19)). - OAuth Flow Simplification & Sign-In Event: Refactored OAuth to remove multi-connection support, added a sign-in event, and provided a Graph API sample application to demonstrate the simplified flow. Commit: e37420d2da3be52deb98aa1b543c677ae0411443 (remove multi-connection oauth support, add signin event, graph sample (#67)). - Development Tools & Internal Libraries Refactor: Updated devtools and refactored internal libraries (code parsing and styling) to improve maintainability and developer efficiency. Commit: ff3f38f6c46ba50ca472b842b306c785634797ca (update devtools (#65)). - Message Extensions Enhancements: Added new 'invoke' card action type and a settings page, with supporting documentation and linting updates to improve usability and reliability of message extensions. Commit: ee14e3b113261428c122316944893a3bc73f1e43 (\`tests/message-extensions\` & other improvements (#213)). Major bugs fixed and reliability improvements: - Streaming Reliability: Close Condition Fix – Corrects the stream close logic to close only when index is 1 and the queue is empty, preventing premature stream termination. Commit: d838215e0bd8da3d8a7f3226952f0bfa0916e6c2 (fix sneaky sneaky bug (#61)). - HTTP Error Body Parsing Robustness – Improves error handling by parsing error bodies correctly for both JSON and plain text, and updates HttpException serialization. Commit: 20d75721a0b5023daf36aff3e158f61e163d837b (fix: http client parsing error body as json when it isn\'t (#62)). - TeamsSettings & SignInEvent Namespace Cleanup – Fixes logic for incomplete configuration detection and aligns SignInEvent namespace usage; updates sample app directives. Commit: b4fb261ef78741a3ac023785e13ad411a0d6e23d (minor bugs fixes (#75)). - CLI Project Detection and Validation Bug Fix (microsoft/teams.ts) – Improves project detection and error messaging when project files like package.json or .sln are not found; validates project environment before CLI operations. Commit: 548f0efcb40d0f90066e855bf2942826f29c6f14 (Fixes cli bugs (#235)). Overall impact and business value: - Increased product reliability and developer productivity across Teams-related tooling, with smoother streaming experiences, robust error handling, and streamlined authentication flows. Expanded extensibility with BotBuilder plugin and message extensions, enabling faster feature delivery and richer integrations for customers. Strengthened maintainability through devtools and internal library refactors, reducing future technical debt and support cost. Technologies and skills demonstrated: - C#/.NET, ASP.NET Core plugin architecture, BotBuilder integration, Graph API usage, error handling patterns, devtools and internal library refactors, testing and linting practices.
