Microsoft Agent Framework adds channels for agents and workflows

This release addresses a common pain point for developers: integrating agents with the channels users already have. By providing protocol-specific packages, Microsoft aims to reduce duplication and maintenance. The shared hosting model lets applications own identity linking, authorization, and state storage, which is important for security and consistency. The emphasis on application-owned session mapping highlights that this framework is flexible but leaves key decisions to the developer. The call for feedback suggests Microsoft is iterating based on community needs, indicating room for growth in this area.
