Migrate a setState StatefulWidget to a Riverpod Notifier in Flutter
A step-by-step move from widget-local setState to a Riverpod 3.x Notifier: classify what actually leaves the widget, write the Notifier, convert to ConsumerWidget, and survive the == filtering, build() re-entry, and autoDispose defaults that bite setState refugees. Tested on Flutter 3.44, Dart 3.x, flutter_riverpod 3.3.2.
Migrate AdMob from Xamarin.Forms to .NET MAUI with Plugin.AdMob
Port your ads layer from Xamarin.Forms to .NET MAUI: what to delete (MTAdmob, custom AdView renderers, Xamarin.GooglePlayServices.Ads bindings), what replaces it in Plugin.AdMob, and a line-by-line API mapping for banner, interstitial, rewarded, rewarded interstitial and app open — plus the singleton-to-DI shift and the UMP consent gap that stops ads serving in the EEA.
Migrate an MCP Server from SSE to Streamable HTTP (2026 Checklist)
The legacy HTTP+SSE transport used two endpoints and a sticky connection. Streamable HTTP uses one. Here is the step-by-step migration for the TypeScript and Python SDKs, the client configs you have to repoint, and the proxy buffering gotcha that makes the new endpoint look broken.
Migrate from blocking .Result/.Wait() calls to async all the way up in a legacy C# codebase
A staged playbook for removing sync-over-async from an existing .NET codebase: inventory with analyzers, measure ThreadPool starvation, convert one call chain at a time, and ratchet the count to zero on .NET 11.

Migrate Copilot Prompt Files to Agent Skills: the Full Checklist
How to convert .github/prompts/*.prompt.md into .github/skills/<name>/SKILL.md so GitHub Copilot loads them automatically. What breaks, what maps 1:1, and how to verify each skill fires.
Migrate Swashbuckle IOperationFilter and ISchemaFilter to OpenAPI transformers in .NET 11
A filter-by-filter porting reference for moving Swashbuckle IOperationFilter and ISchemaFilter code to the built-in operation and schema transformers in .NET 11, with the context-object field mapping and the Microsoft.OpenApi v2 changes that bite.
Migrate a Custom Tool-Calling Loop to an MCP Server (TypeScript, 2026)
A step-by-step checklist for lifting a hand-rolled Anthropic tool-calling loop onto a standalone MCP server. The tool bodies move almost verbatim; what changes is where the schema comes from, how results are wrapped, and how errors cross the process boundary.
Migrate a LangChain Agent to the MCP Tool-Calling Pattern
A step-by-step checklist for moving an existing LangChain agent off inline @tool functions onto a standalone MCP server that any client can call. Covers extracting tools into FastMCP, re-wiring the agent with langchain-mcp-adapters MultiServerMCPClient, the sync-to-async switch, transports, and the gotchas that bite mid-cutover.
