Review Summary

This PR correctly addresses Issue #164 by removing the deprecated FluentValidation.AspNetCore package. The changes are minimal, focused, and well-documented. LGTM ✅

Detailed Feedback

✅ Package Migration (test/MicroElements.Swashbuckle.FluentValidation.Tests/MicroElements.Swashbuckle.FluentValidation.Tests.csproj:16)

• Correct replacement: FluentValidation.AspNetCore 11.3.1 → FluentValidation.DependencyInjectionExtensions 12.0.0
• The replacement is appropriate since FluentValidation.AspNetCore was deprecated in FluentValidation 11.0 and removed entirely
• FluentValidation.DependencyInjectionExtensions is the official successor package that provides the DI registration methods (AddValidatorsFromAssemblyContaining, AddValidatorsFromAssembly, etc.)
• Consistency confirmed: All sample projects already use FluentValidation.DependencyInjectionExtensions 12.0.0, so this aligns the test project with the rest of the codebase

✅ Version Bump (version.props:4)

• Version increment from 7.0.4-beta.2 → 7.0.4-beta.3 is appropriate for a dependency update in a pre-release version
• Follows semantic versioning conventions for beta releases

✅ Changelog (CHANGELOG.md:1-4)

• Well-structured entry with clear description of what was changed and why
• Correctly references Issue Get rid of deprecated package FluentValidation.AspNetCore #164
• Explains the rationale (aligning with sample projects, using non-deprecated successor)
• Changelog format is consistent with the rest of the file

Test Coverage

According to your test plan:

• ✅ Build succeeds with 0 errors
• ✅ All 54 tests pass on .NET 8.0 and .NET 9.0
• ✅ All 51 tests pass on .NET 10.0

The fact that all tests pass confirms that FluentValidation.DependencyInjectionExtensions provides all the necessary functionality previously obtained from FluentValidation.AspNetCore.

Minor Observations

No issues found. The PR is clean and focused on the single task of replacing the deprecated package.
