ASP.NET Core's validation source generator now correctly unwraps array types, closing a gap that could slip validation past your models.

The aspnetcore team shipped a fix [1] for array type unwrapping in the validation source generator, a subtle but critical issue where nested array validation wasn't being properly generated. This closes a validation gap that could let malformed data through if you're relying on source-generated validators. Meanwhile, msbuild is keeping pace with the ecosystem: Roslyn's latest build [2] landed in main, pulling the July 9 compiler improvements into the build pipeline, and NuGet 7.9.0.77 [3] synced simultaneously to keep package management aligned. These dependency rolls are routine but important - they mean your builds will have access to Roslyn's latest analysis capabilities and NuGet's package resolution fixes without waiting for a major release.
