Hands-on testing with the samples app surfaced two Preview 5 ASP.NET Core features that weren't in the first draft: async form validation (dotnet/aspnetcore #66526) and resource-based validation localization (dotnet/aspnetcore #66646). Both ship together and are foundational for the SSR client validation section, so add dedicated sections covering the EditContext.AddValidationTask / IsValidationPending API and the AddValidationLocalization<T> wire-up.

Found via a milestone cross-check sweep against the draft: PR #65650 was merged into main on 2026-05-14 with labels area-mvc,feature-openapi but no 11.0-preview5 milestone tag, which kept it off the editorial scoring pass's radar even though it changes user-visible MVC + minimal API + OpenAPI behavior. Adds a dedicated section under the OpenAPI cluster. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

I posted the re-worked sections as regular comments to avoid problems with code blocks inside suggestion blocks.
Feel free to make the sections shorter if there is too much detail. However, the original texts were confusing and leaking implementation details.
- Rewrite Blazor validation sections (SSR client-side, async, localization) per @oroztocil's suggestions - Update TOC entries to match new section titles - Rewrite #65650 OpenAPI paragraph per @mikekistler's suggestion (and drop the leaked vscode-file URL) - Remove @cincuranet from community contributors per @Youssef1313 (not a community contributor) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
