Extract OpenAPI specs from #dotnet web apps automatically. Fail CI checks if the spec isn't synced with #csharp code, validate it against Spectral rules, and catch breaking changes. All handled at build time by a single NuGet package made at Workleap.

We automate API specs as first class citizens, keeping them versioned, validated, and checked for breaking changes in ASP.NET Core projects.

I've been working with JavaScript since the days when browser compatibility was our biggest headache. Supporting IE6 and the original Edge alongside Chrome and Firefox felt challenging at the time. But that was nothing compared to today's reality.

I went on holiday for two weeks and I feel like VSCode + Copilot improved a lot in just that little time.
It feels a lot smoother and better predictions.

My favorite dev tool this year has been Proxyman. It's a well crafted super useful tool for anyone working with HTTP APIs.
Money very well spent!

Is there a way to auto install .NET runtimes I'm going to need based on the .NET project I'm about to run and then install the necessary runtimes in GH actions?
The .NET install action is very helpful, but you have to specify the versions yourself.

TLDR: I moved to Brooklyn and joined Fern to ensure .NET developers get the best .NET SDKs possible, idiomatic and performant.

If you're a developer trying to adopt a new HTTP and/or WebSocket API, which resources would empower you to be successful quickly, beyond the basics like docs and API references?
For example, we just released a Postman collection. Any tools I should look into?

I just launched a new version of the AssemblyAI app for Zapier.
The enhanced app is more flexible, supports more Speech AI features, and integrates more closely into the Zap editor.

After recent discussions about C# events and their drawbacks, prototyped a couple of alternative event APIs for a Speech-To-Text library that I'm working on.

Please let me know which one you prefer, or better alternatives. 🙇
