Pull Request Overview
This PR removes the package baseline infrastructure from the ASP.NET Core repository. The baseline system was previously used to ensure consistent package dependencies across servicing builds by tracking the last RTM release versions and preventing breaking changes to package dependencies.
Key Changes:
- Removed the BaselineGenerator tool and all baseline validation logic from the build system
- Deleted baseline data files (Baseline.xml and Baseline.Designer.props)
- Updated documentation to remove references to baseline management
