Miles to go before I sleep...

@pactechnologies @SahilExec Why so?

[Md. Redwan Hossain @redwan_ping]

@Enea_Jahollari I would choose postgres

@EddCoates Just add google/social login, this approach sucks but it will work.

[Md. Redwan Hossain @redwan_ping]

@MuwaffaqBadawi How loop is related with software design? It's just a language feature to work with iterative use-case.

[Md. Redwan Hossain @redwan_ping]

@MuwaffaqBadawi Visual studio doesn’t even have fluent UI design of windows 11. The latest has some UI improvement but not even close with other native windows UI.

@MuwaffaqBadawi @sterenas @wdolek rider has a graphical tool built in to work with efcore. I was talking about that.

[Md. Redwan Hossain @redwan_ping]

@iammukeshm What's the benefit? It's still for dev only. I still have to write compose for staging/production.

[Md. Redwan Hossain @redwan_ping]

@sterenas @wdolek @MuwaffaqBadawi Smooth resharper experience, Ef core tools

[Md. Redwan Hossain @redwan_ping]

@driscollis Horrible syntax, completely unreadable.

[Md. Redwan Hossain @redwan_ping]

@KarenPayneMVP Why interface for entities?

[Md. Redwan Hossain @redwan_ping]

@SeniorLazarus @anshuc @github Seems like the same scam where company owners fires up their own business just to claim insurance.

[Md. Redwan Hossain @redwan_ping]

@mjovanovictech Create, Update, Get, GetAll, Delete. Each one has now atleast 2-4 files. It was before just controller, service, repository (not mandatory), dto.

[Md. Redwan Hossain @redwan_ping]

@kristijan_kralj Write the entire codebase in Program.cs file. Easy right?

[Md. Redwan Hossain @redwan_ping]

@hiwinit Never. I just hate the idea.

[Md. Redwan Hossain @redwan_ping]

@shadcn Make it possible for angular.

[Md. Redwan Hossain @redwan_ping]

@catalinmpit That's why signal driven modern angular rocks for internal application. The core pattern remains the same for 10+ years.

[Stefan Đokić | .NET @TheCodeMan__]

p95 went from 2270 ms to 217 ms.

Throughput went from 168 RPS to 1,238 RPS.

I changed exactly one line of code.

Thread.Sleep(200) ➜ await Task.Delay(200, ct)

That's it.
Same machine.
Same 400 concurrent users.
Same 200 ms of "work."

The reason it matters this much: Thread.Sleep parks an OS thread. The thread pool only grows at 1–2 threads per second after MinThreads is exceeded.
So with 400 VUs hammering a sync endpoint, requests aren't slow because the work is slow, they're slow because they're queued waiting for a thread that doesn't exist yet.

await Task.Delay returns the thread to the pool while it waits.
Suddenly, 16 threads can serve 400 concurrent requests instead of 16.

I built a .NET 10 lab project that reproduces this on demand and produced the numbers above on a Ryzen 7 4800H. Code + k6 scripts + step-by-step breakdown.

Will share it in 2h in my Newsletter. Join 20k+ engineers and read it: https://t.co/EO5uHB2wVy

@cagataycivici Awesome. Can't wait to try out.
