Одна строчка .Result роняет ваш ASP.NET Core при CPU 8 %: разбор hill-climbing в .NET 9

TL;DR. Один «безобидный» foo.GetAsync().Result в middleware способен превратить ASP.NET Core, державший 50k RPS с p99 = 40 мс, в сервис с 12k RPS и p99 = 4 с — при CPU 8 %. Виноват не сам blocking call, а hill-climbing — фидбэк-луп в ThreadPool, в недрах которого живёт дискретное преобразование Фурье. Разбираем по исходникам CoreCLR, почему это вообще возможно, воспроизводим эффект на ~80 строках кода и разбираемся, почему SetMinThreads — не решение, а анестезия.

.NET Short Term Releases get 2 years of support!

Earlier, the short term releases for each .NET version would last only 1.5 years (18 months), which means that once an LTS gets released, you’ll have to upgrade to that LTS versions before your .NET version gets deprecated. Now, it seems that Microsoft have adjusted this support length for short term releases of the modern .NET framework, starting from .NET 9.0 released November 12th of the last year.

Microsoft has added six more months to the total support length for such releases, making them end with their LTS version that came before. For example, on November 10th, 2026, both .NET 8.0 and 9.0 will reach end of life.

Here’s the chart that demonstrates the new support timeline:

This is a welcome change, as you’ll now have six extra months to upgrade to the new LTS release by the time the current STS and LTS versions are still in support. You can learn more about this change here.

Solving the #NET9 #MAUI #RefreshView Limitation on #macOS: building a MAUI CustomRefreshView from scratch for all platforms

http://puresourcecode.com/dotnet/maui/building-a-maui-customrefreshview/

Spannend! #dotnetMaui mit #net9
- iOS App ist als Release signifikant kleiner! Wir reden von ca 20 statt 60 MB
- Android App dagegen deutlich größer?! Um 90 statt um 60 MB - Nanu?
Werde recherchieren müssen ob es neue Schalter gibt oder was da los ist. 🤔
