Microsoft's Agent Framework gives.NET builders a first-class way to intercept an agent mid-run

The 1.19.0.NET release on 22 August makes the agent-hooks interception contract an experimental first-class feature, and adds chat-client routing that survives across a session. The same release forwards extra context through the agent-user interface layer and fixes streaming artifact updates on agent-to-agent calls.

What it means A supported interception point is the difference between auditing what an agent did and only reading about it afterwards.
