-# Azure DevOps (OneBranch) placeholder pipeline for AppConfiguration-DotnetProvider.
-#
-# TEMPORARY validation pipeline. It does NOT build or run tests yet - it only:
-#   1. Confirms pull requests trigger this pipeline in Azure DevOps.
-#   2. Confirms Azure login works via the shared ARM service connection.
-#   3. Logs a message.
-#
-# Once verified, this will be replaced with the full build + integration-test
-# pipeline. Per GitHub inside Microsoft (GiM) guidance (https://aka.ms/gim/pipelines),
-# it extends the OneBranch governed templates - the same setup the OOBReleases
-# pipeline uses for this repo. Create it via StartRight (Governed Pipeline) in the
-# msazure / "Azure AppConfig" project with the "I'm creating a OneBranch pipeline"
-# box CHECKED. StartRight reads the YAML from the default branch, so this file
-# must be on main.
