Code Review

Type: Dependency update (minor)

Change:10.2.0 → 10.3.0 in TUnit.Core/TUnit.Core.targets

---

Assessment: Approve

This is a clean, routine minor version bump with no logic changes. The single-line modification correctly updates _TUnitPolyfillVersion in the MSBuild targets file.

What's new in Polyfill 10.3.0 — relevance to TUnit:

• ConfigureAwaitOptions polyfill for pre-net8.0 — Directly relevant: TUnit uses this polyfill for netstandard2.0, netstandard2.1, and .NETFramework targets, and ConfigureAwaitOptions is a net8.0 addition. Downstream consumers on older frameworks will benefit.
• Os polyfill fix (PR #538) — Bug fix for OS detection; low risk.
• RequiresAssemblyFilesAttribute polyfill — Aligns well with TUnit's AOT-compatibility requirements (CLAUDE.md mandates AOT support and proper [DynamicallyAccessedMembers] annotations).

No concerns. The version bump is minimal and the new additions are additive/backwards-compatible. The auto-merge + squash configuration is appropriate for this kind of routine dependency update.
