Microsoft.Extensions.AI.OpenAI 10.10.1 Fixes the OpenAI 2.14 TypeLoadException

OpenAI 2.14.0 renamed GlobalMcpToolCallApprovalPolicy, which broke every tool-carrying Responses call through Microsoft.Extensions.AI.OpenAI 10.10.0. Version 10.10.1 moves to OpenAI 2.14.0 and also picks up the null reasoning status fix for OpenAI-compatible endpoints.

Fix: ASP.NET Core returns 400 "The X field is required" for a non-nullable string property

With <Nullable>enable</Nullable>, MVC treats every non-nullable reference type as [Required(AllowEmptyStrings = true)]. Mark optional properties as string?, give them a default, or set SuppressImplicitRequiredAttributeForNonNullableReferenceTypes.

Fix: e: Daemon compilation failed: null in a Flutter Android Gradle build

Fix: Failed to decode advisories for archive from https://pub.dev in flutter pub get

The advisories warning in pub get is harmless: pub get exits 0. pub.dev fixed the bad response on 2026-05-04. If you still see it, the cause is a mirror or proxy.

How to Keep API Keys Out of a Coding Agent's Context With a Credential Gateway

Scoping a token does not stop a prompt-injected agent from leaking it. Moving the token out of the agent's process does. Three working setups: a 50-line gateway any agent can call, Claude Code 2.1.199+ sandbox masking with injectHosts, and Claude Managed Agents vaults, plus the measured leak that host-level injection still allows.

Refit 16.1 Writes Your Paging Loop: PagedEnumerable, [Paged] and [PageToken]

Refit 16.1.0 lets an interface method return PagedEnumerable<TPage, TItem>, and the source generator emits the request-per-page loop for cursors, offsets, response headers and next links. Here is how to declare it, how enumeration behaves, and the RF013 build error you get for a misspelled member.

2026-09-24 errors aspnet-core blazor

Fix: Conflicting assets with the same target path after upgrading to the .NET 10 SDK

On the .NET 10 SDK every Microsoft.NET.Sdk.Web project gets StaticWebAssetBasePath=/, so a web app referencing another web app collides. Set the base path on the referenced project. Disabling compression does not help.

2026-09-24 errors dotnet dotnet-10

Fix: HttpIOException: The response ended prematurely from HttpClient in .NET

HttpClient reuses a keep-alive connection the server just closed, or the server drops the connection mid-response. Lower PooledConnectionIdleTimeout below the server's idle timeout and retry only idempotent requests.

2026-09-24 errors blazor aspnetcore

Fix: Unable to find the required 'IAuthenticationService' service with [Authorize(Policy = ...)] in Blazor

A Blazor Web App page with [Authorize] becomes an endpoint the AuthorizationMiddleware checks, and a failed check calls ChallengeAsync, which needs AddAuthentication. Register a real scheme, or pass component endpoints through to AuthorizeRouteView.
