Migrate from Newtonsoft.Json 13 to System.Text.Json in a large .NET 11 codebase
A version-pinned playbook for swapping Newtonsoft.Json 13.0.4 for the in-box System.Text.Json on .NET 11: the attribute and settings mappings, the defaults that silently change your wire format, a staged rollout strategy, verification, and the gotchas that bite large codebases.
The Dart and Flutter MCP server: one command to give Claude Code your running Flutter app
Dart 3.12 ships dart mcp-server, the official MCP bridge into the Dart and Flutter toolchain. Register it once in Claude Code, Cursor, or Codex CLI and your agent gets hot reload, pub.dev search, and live widget introspection without copy-pasting a DTD URI.
Fix: HTTP MCP Server URL Won't Connect in Claude Desktop (stdio vs HTTP Transport)
Claude Desktop's claude_desktop_config.json only validates stdio servers. Drop a 'url' field in and it silently strips the entry, crashes on startup, or boots with zero tools. Use a custom connector for remote URLs and mcp-remote as a stdio bridge for local HTTP servers.

Dart records vs Freezed classes: which should you pick in 2026?
Pick Dart 3.12 records for ephemeral, locally-shaped data with no methods, and Freezed 3.x classes for named domain models that need copyWith, sealed unions, JSON serialization, or any behaviour.
Flutter vs React Native vs .NET MAUI: which should you pick for a new mobile project in 2026?
For a greenfield mobile app in 2026, pick Flutter 3.44 when pixel-identical UI and animation budget matter, React Native 0.82 when your team already lives in TypeScript and you need a real browser sibling, and .NET MAUI 11 when iOS and Android are part of a wider .NET product and you need first-party Microsoft support.
