A step-by-step migration from an inline FutureBuilder widget to a Riverpod AsyncNotifier in a real Flutter app: move the async work out of build, expose it as a provider, render with .when() or switch pattern matching, and add refresh and mutation methods. Tested on Flutter 3.44, Dart 3.x, flutter_riverpod 3.3.2.

Reading session state in static server-rendered Blazor meant reaching into HttpContext.Session and serializing by hand. .NET 11 Preview 5 adds [SupplyParameterFromSession] so a component property binds to a session key directly.

By default a local Cursor SDK agent runs every tool call without asking. Set local.autoReview to route Shell, MCP, and Fetch calls through the classifier, then steer it with the autoRun block in permissions.json. With code, the three-step evaluation order, and why none of it is a security boundary.

A version-pinned guide to moving a legacy Flutter 2.x app to a current Flutter 3.x release, with the sound null safety migration as the hard gate: why you need a two-hop path through Dart 2.19, what dart migrate does, and what breaks along the way.

A step-by-step migration from Swashbuckle.AspNetCore to Microsoft.AspNetCore.OpenApi in .NET 11: swapping AddSwaggerGen for AddOpenApi, converting operation, schema, and document filters to transformers, keeping a UI, and the Microsoft.OpenApi v2 breaking changes that bite.

A step-by-step migration from the provider package to Riverpod 3.x in a real Flutter app: ChangeNotifierProvider to Notifier, MultiProvider to ProviderScope, context.watch to ref.watch, ProxyProvider to ref.watch composition, plus the equality and lifecycle gotchas that bite. Tested on Flutter 3.27.1, Dart 3.11, provider 6.1.5, flutter_riverpod 3.3.1.

Use AsNoTracking for read-only queries by default. Reach for AsNoTrackingWithIdentityResolution only when the result graph contains the same entity more than once and your code depends on getting a single shared instance back.

For months availableModels restricted the model picker but left the Default option wide open. Claude Code 2.1.175 adds enforceAvailableModels so admins can finally pin a strict model allowlist.

Use FutureBuilder or StreamBuilder for a self-contained, throwaway async widget. Reach for Riverpod AsyncValue once the result is shared, cached, or mutated. Here is the decision, the gotchas, and runnable code for both. Tested on Flutter 3.44 and flutter_riverpod 3.3.1.

Use the built-in source-generated validation for synchronous, attribute-expressible rules in ASP.NET Core 11; reach for FluentValidation when you need async rules, complex cross-field logic, or validation kept out of your domain models.
