A step-by-step checklist for moving a .NET app off the raw OpenAI 2.12 SDK onto the provider-neutral Microsoft.Extensions.AI 10.7 IChatClient. Covers the AsIChatClient bridge, the CompleteChatAsync-to-GetResponseAsync rewrite, streaming, tool calling, DI registration, and the gotchas that bite mid-cutover.

A step-by-step upgrade from flutter_riverpod 2.x to 3.x: bump the packages, move StateProvider and friends to the legacy import, drop the AutoDispose and Family ref types, handle ProviderException wrapping and automatic retry, and fix the == notification filtering that silently drops StreamProvider events.

VS Code 1.128 (July 8, 2026) lets one Claude agent-host session hold several parallel chats, each with its own history, title, and model. Here is what chat.agentHost.enabled actually unlocks and how the quick-chat and BYOK pieces fit.

Trim-safe code is code the .NET trimmer can statically prove is reachable, so it survives when unused code is removed from a self-contained app. This is the practical guide: turn on the analyzer, drive every IL2xxx warning to zero, annotate reflection with DynamicallyAccessedMembers, propagate RequiresUnreferencedCode to public APIs, and replace unanalyzable patterns with source generators.

Claude Sonnet 5 (claude-sonnet-5) shipped June 30, 2026 and now backs the 'sonnet' alias in Claude Code. Its new tokenizer emits about 30% more tokens for the same text, so cost estimates and max_tokens limits tuned for Sonnet 4.6 need a recount.

A step-by-step guide to moving seed data off HasData and onto UseSeeding and UseAsyncSeeding in EF Core 11, including the DeleteData migration trap that wipes your existing rows if you skip it.

Flutter 3.44 exposes the device's rounded display corners through MediaQuery.displayCornerRadiiOf. Stop guessing a magic radius and clip your UI to the exact hardware curve on Android API 31+.

go_router and auto_route both sit on top of Navigator 2.0, so the real choice is declarative URL routing vs code-generated typed routes vs hand-rolling the Router API. A decision matrix with config for each, and when raw Navigator still wins.

A step-by-step checklist for moving an existing Semantic Kernel 1.77 .NET app to Microsoft Agent Framework 1.13. Covers the Kernel-to-AIAgent rewrite, plugins-to-tools, thread-to-session, the KernelFunction compatibility bridge, DI changes, and the gotchas that bite mid-cutover.
