Summary

Updates Polyfill dependency from 9.6.0 to 9.7.0 (minor version bump).

Critical Issues

None found ✅

Verdict

✅ APPROVE - No critical issues

This is a straightforward dependency update for a compile-time only package. The Polyfill package is properly configured with PrivateAssets=all and runtime exclusions, so it only affects compilation for older framework targets (netstandard2.0/2.1, .NETFramework) and has no runtime impact.

Summary

Updates Polyfill dependency from 9.6.0 to 9.7.0 in MSBuild targets.

This is a straightforward dependency update with no code changes. The Polyfill package is used for compile-time type generation in older target frameworks (netstandard2.0/2.1 and .NET Framework), and the version bump is minimal (9.6.0 → 9.7.0).

No TUnit critical rules are violated:

• No source generator or reflection changes (Rule 1, 5)
• No snapshot updates needed (Rule 2)
• No VSTest dependencies involved (Rule 3)
• No performance impact (Rule 4)

Verdict

✅ APPROVE - No critical issues
