Asp.Versioning 10.0 is the first release that targets .NET 10 and the new Microsoft.AspNetCore.OpenApi pipeline. Sander ten Brinke's April 23 walkthrough shows how to register one OpenAPI document per API version with WithDocumentPerVersion().

Upload multi-GB files to Azure Blob Storage from .NET 11 without loading them into memory. BlockBlobClient.UploadAsync with StorageTransferOptions, MultipartReader for ASP.NET Core uploads, and the buffering traps that put your payload on the LOH.

Claude Code v2.1.119 expands --from-pr beyond github.com. The CLI now accepts GitLab merge-request, Bitbucket pull-request, and GitHub Enterprise PR URLs, and a new prUrlTemplate setting points the footer PR badge at the right code-review host.

A practical, version-specific playbook for cutting .NET 11 Lambda cold starts. Covers Native AOT on provided.al2023, ReadyToRun, SnapStart on the managed dotnet10 runtime, memory tuning, static reuse, trim safety, and how to actually read INIT_DURATION.

Three ways to put Claude Code on a schedule that triages GitHub issues unattended in 2026: cloud Routines (the new /schedule), the claude-code-action v1 with cron + issues.opened, and the session-scoped /loop. Includes a runnable Routine prompt, a complete GitHub Actions YAML, jitter and identity gotchas, and when to pick which.

A complete .NET 11 walkthrough for shipping an ASP.NET Core minimal API with Native AOT: PublishAot, CreateSlimBuilder, source-generated JSON, the AddControllers limitation, IL2026 / IL3050 warnings, and EnableRequestDelegateGenerator for library projects.

EF Core builds its conceptual model lazily on the first DbContext access, which is why the first query in a fresh process is several hundred milliseconds slower than every query after it. This guide covers the three real fixes in EF Core 11: a startup IHostedService that touches Model and opens a connection, dotnet ef dbcontext optimize to ship a precompiled model, and the cache-key footguns that silently rebuild the model anyway.

A complete guide to global exception handling in ASP.NET Core 11: why IExceptionFilter is the wrong tool, how IExceptionHandler and UseExceptionHandler work together, ProblemDetails responses, multi-handler chains, and the .NET 10 diagnostics suppression breaking change.

Build a working Model Context Protocol server in C# 14 / .NET 11 using the official ModelContextProtocol 1.2 SDK. Covers stdio transport, [McpServerTool] attributes, dependency injection, the stderr logging trap, and registration with Claude Code, Claude Desktop, and VS Code.

Mocking DbContext directly silently breaks ChangeTracker, which is why Microsoft discourages it. This guide shows the two patterns that actually work in EF Core 11: SQLite in-memory with a kept-open connection so the real ChangeTracker runs, and the repository pattern that lifts EF Core out of the test entirely.
