dotnet-1.23.0
Microsoft Agent Framework release dotnet-1.23.0 introduces breaking changes including tool support updates across runs, package dependency bumps, approval enforcement, and configuration key allowlisting, alongside security and workflow fixes.
Why this signal matters
The Microsoft Agent Framework release dotnet-1.23.0 contains several breaking changes and functional updates across the .NET implementation. Key breaking changes include enhanced support for tool modifications between runs, stricter enforcement of approval response bindings, fixes to DevUI approval continuation, an allow list for configuration keys, and dependency updates bumping Azure.AI.Projects to 3.0.0-beta.3, OpenAI to 2.14.0, and MEAI to 10.10.1. Security and stability updates address approval logic—specifically fixing an issue where invoke function tools could bypass approval and ensuring approval state is only consumed upon successful runs. Additionally, origin pinning has been added to the Foundry toolbox MCP client, AGUI SDK packages have been bumped to 1.0.0, and core updates fix tool call argument parsing and declarative workflow variable handling.
Actionable summary
dotnet-1.23.0 brings multiple breaking changes to .NET agent pipelines: enforced approval response binding, strict configuration key allowlists, updated tool state management between runs, and dependency bumps (Azure.AI.Projects 3.0.0-beta.3, OpenAI 2.14.0, MEAI 10.10.1). It also patches a bug where function invocations could bypass approvals and adds origin pinning for the Foundry MCP client.

What builders should check
- Review application configuration keys to align with the new allow list enforcement.
- Verify tool definition handling and approval response bindings across execution runs.
- Update project dependencies to support Azure.AI.Projects 3.0.0-beta.3, OpenAI 2.14.0, and MEAI 10.10.1.
- Validate human-in-the-loop and DevUI approval workflows to ensure compliance with fixed approval continuation logic.
