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.

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.

A step-by-step guide to converting $-interpolated ILogger calls into message templates and [LoggerMessage] source-generated methods on .NET 11: what breaks, how to sweep a codebase with CA2254, how to verify the JSON state, and how to roll back.

A decision guide for ASP.NET Core 11: middleware runs for every request before your handler binds, endpoint filters run only for the matched endpoint after binding and can see the typed arguments. Includes a feature matrix, when-to-pick-each scenarios, the ordering rules, and the gotchas that force the choice.

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.

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.

A practical, end-to-end guide to monetizing a .NET MAUI app with Google AdMob using Plugin.AdMob. Install one NuGet, call UseAdMob(), and wire up banner, interstitial, and rewarded ads — with consent built in via UMP, test ad units, the exact service APIs, preloading patterns, and a production checklist. Tested on .NET 10 / MAUI.

await is the right answer almost every time. When you truly must block, GetAwaiter().GetResult() beats .Result and .Wait() because it throws the original exception. A decision matrix for .NET 11 and C# 14.

Cancelling the CancellationToken you pass to InvokeAsync now reaches the server and cancels the hub method. This closes a SignalR request open since 2019.

Version 2.1.218 moves /code-review off your main conversation into a background subagent, and fork-context skills now background by default. Here is what changed and how to opt out.
