ASP.NET 10.0.11

Release Date: August 11, 2026

ASP.NET Core 10.0.11 — Released August 11, 2026. This is the latest servicing update for the .NET 10 wave of ASP.NET Core, spanning the full changelog from v10.0.10 to v10.0.11. It contains one notable functional backport, dependency refreshes, and infrastructure improvements.

Overview

ASP.NET Core 10.0.11 is a patch-level servicing release that ships alongside .NET 10.0.11. The update targets stability in Blazor Server circuit handling, updates key data-access and OpenAPI dependencies, and moves Linux CI off Microsoft-hosted pools. No new public APIs are introduced.

Notable Fix

Blazor Server circuit state — A backported fix (PR #67453, by @oroztocil) improves handling of expired client-persisted circuit state, closing a gap where stale persisted state could surface after a circuit had already been terminated.

Dependency Updates

OpenApi updated to 2.7.5 — the OpenAPI integration now tracks the 2.7.x line, with Microsoft.OpenApi additionally constrained to disallow a next-major jump (#67464, #67772).
Microsoft.Data.SqlClient 6.1.1 — the SqlClient reference is bumped to 6.1.1 (#67811).
MessagePack-CSharp — submodule reference updated (#67528).
googletest — native test dependency refreshed twice (#67529, #67653).

Fixes and Maintenance

Fixed flaky CanElevateEffectiveMaxItemCount_WhenOverscanExceedsMax test (#67705).
Source code updates synced from dotnet/dotnet across multiple PRs (#67643, #67658, #67708, #67728).
Linux CI jobs moved off Microsoft-hosted pools (backports of #64842 and #65867), by @mmitche.

Deprecations

None. This servicing release introduces no deprecations or breaking changes; existing applications on 10.0.x can upgrade in place.
