032 | SharePoint Framework v1.23 GA & M365 Copilot with Interactive UX… via SPFx?

May 20, 2026 / 56:55/E32

In this episode, Andrew and Julie dig into the SharePoint Framework (SPFx) 1.23 release that went generally available on May 13, 2026. They walk through what's actually in the release, including the new command set grouping support, the deprecation of the hosted workbench (and the community PnP project filling that gap), and the long-awaited new and edit panel override support for lists and libraries landing in 1.23.1. They also unpack the move away from the Yeoman generator toward an open source SPFx CLI, why the open template model has Julie watching the security implications, and Stefan Bauer's running list of issues with the heft build toolchain that anyone doing non-trivial styling should be tracking.

From there, the conversation turns to where SPFx and Microsoft 365 Copilot are heading. Andrew connects the dots on a cryptic roadmap bullet about "SPFx-powered UX for Copilot built with the MCP app model," explaining how MCP apps work today and why this could mean web part developers get Copilot chat surfaces for free, similar to how SPFx tabs work in Microsoft Teams. They wrap with the public preview of the Microsoft 365 Copilot Agent Evaluations Tool for declarative agents built with the Microsoft 365 Agents Toolkit, why evals matter when models and orchestrators shift underneath you, and Julie's pragmatic take on leaning on AI to call deterministic tools rather than expecting deterministic AI.
