Pull request overview
Note
Copilot was unable to run its full agentic suite in this review.
Documents that the polling-based Azure Functions Blob trigger isn’t supported for ADLS Gen2 / hierarchical namespace (HNS)-enabled storage accounts, and recommends using the Event Grid-based trigger instead (per azure-sdk-for-net#56909).
Changes:
- Adds a storage considerations footnote clarifying lack of official support for triggers on ADLS/HNS-enabled accounts.
- Adds a prominent note to the Blob trigger reference recommending the Event Grid-based implementation for ADLS/HNS-enabled accounts.

Microsoft.Azure.WebJobs.Extensions.Storage.Blobs SDK does not support Datalake Files or HNS enabled accounts.
This need to be publicly document as it should be using Event Grid over the Blob Trigger polling mechanism.
