Bot Framework DotNet SDK 4.23.1

Final Release of Bot Framework DotNet SDK

Bot Framework DotNet SDK has reached end-of-life. This is the last planned release. This project will no longer be updated or maintained. Customers using this SDK will not be disrupted. However, the SDK will no longer be supported through service tickets in the Azure portal and will not receive product updates.

To build agents with your choice of AI services, orchestration, and knowledge, consider using the Microsoft 365 Agents SDK. The Agents SDK is GA and has support for C#, JavaScript or Python. You can learn more about the Agents SDK at aka.ms/agents. If you're looking for a SaaS-based agent platform, consider Microsoft Copilot Studio. If you have an existing bot built with the Bot Framework SDK, you can update your bot to the Agents SDK. You can review the core changes and updates at Bot Framework SDK to Agents SDK migration guidance here. Support tickets for the Bot Framework SDK will no longer be serviced as of December 31, 2025.
