Description

gRPC channels are cached per configuration (endpoint, task hub, credential type, etc.). If options are changed after the first channel is created (e.g. via IOptionsMonitor.OnChange or options reload), the cached channel is not updated and will keep using the original configuration until the process restarts or the service provider is disposed.

Research direction

Start by tracing where gRPC channels are cached per configuration and how IOptionsMonitor.OnChange or options reload flows through that path. Check the behavior after options change and define completion as cached channels no longer retaining the original configuration until process restart or service-provider disposal.
