dotnet/aspnetcore v10.0.5 → v10.0.6 — release digest

ASP.NET Core 10.0.6 is a small servicing release focused on regressions in Blazor, JsonPatch, templates, and IIS hosting. Most of the remaining work is dependency flow and build/package maintenance.

What's new

Blazor no longer treats framework metadata comments as logical elements during rendering. This fixes navigation failures and insertBefore JavaScript errors when moving between pages that use different render modes such as InteractiveServer, InteractiveWebAssembly, and InteractiveAuto (#64530).

Fixes

Fixed a regression in Microsoft.AspNetCore.JsonPatch where previously accepted PATCH requests with Content-Type: application/json started returning 415, and removed the package dependency that caused Blazor WebAssembly projects using JsonPatch to fail to build. The SystemTextJson JsonPatch types are unaffected (#65674).
Fixed the shipped app.db in the Blazor Web App template with Individual authentication so its EF Core migration history matches the template source. This restores dotnet ef database update without hitting errors about identity tables already existing (#65532).
Fixed a shutdown hang for IIS-hosted apps when Preload Enabled = true, where machine shutdown could get stuck as worker processes were repeatedly restarted. The workaround restores the earlier non-blocking host lifetime behavior for this scenario (#65761).

Other notable changes

Updated the SharedFx and Targeting Pack MSI build to use WiX 5, bringing those installers in line with the rest of the packaging toolchain (#65651).
Updated ASP.NET Core to newer code and dependency snapshots from dotnet/dotnet, dotnet/extensions, and internal optimization packages (#65401, #65495, #65499, #65506, #65602, #65604, #65533, #65649, #65654, #65687, #65695, #65707, #65713, #65721, #65739, #65799).
Various build and test reliability updates landed for servicing, including fixes around template test package resolution, restore serialization, and packaging/test infrastructure (#65781, #65796, #65798, #65688, #65669, #65691, #65672).
