The repo nuget.config clears all package sources and declares only ORT-Nightly. Upstream CI resolves Microsoft.Windows.AI.MachineLearning through internal package infrastructure, so a USE_WINML build outside that environment has no source for the WinML SDK and its dependencies. Adding nuget.org alone is not enough: ORT-Nightly is an upstream-proxying feed that answers 401 (prompting for credentials) rather than 404 for packages it does not host, which aborts the restore instead of falling through to the next source. A packageSourceMapping routes the ORT packages to the nightly feed and everything else to nuget.org. Verified with an uncached, non-interactive install of the WinML SDK, and by a cold USE_WINML=ON + USE_DML=ON build.
