Pull request overview
This PR updates the .NET AGUI ASP.NET Core hosting endpoint to integrate with the core hosting AgentSessionStore abstraction, enabling session persistence across requests (keyed by AG-UI thread ID). It also adds/updates tests and a sample to demonstrate the DI + in-memory session store setup.
Changes:
- Add
MapAGUIoverloads that resolve a named agent from DI (viaIHostedAgentBuilderoragentName). - Wrap agent execution with
AIHostAgentand persist/restore sessions using a keyedAgentSessionStore(fallback to noop when not registered). - Add unit/integration tests and update the end-to-end sample to use
WithInMemorySessionStore.
