Today I will… debug a production crashDevBlogs | Visual Studio Blog | September 22, 2026We’ve all experienced this, the desktop application is hanging, the window is greyed out, and we’re just waiting for it to start to respond. Or we’re on a website and are sure that it was going to load faster than this, but we’re just waiting the loading icon spin around and around. These sorts of problems, when they happen in production, can be difficult to diagnose since you often need to replicate them, from machine specifications to traffic loads.Today we’re going to look at one of the possible problems, having too many active threads running in a C# application, and how we can debug the crash after the fact using a memory dump.https://devblogs.microsoft.com/visualstudio/today-i-will-debug-a-production-crash/

Creating a memory dump in C#DevBlogs | .NET Blog | September 22, 2026When applications crash in production, how much do we actually know about what happened? And more importantly, how easy is it to debug what happened so that we can fix the bug? Let’s learn how easy it is to capture a memory dump so that we can debug it.https://devblogs.microsoft.com/dotnet/creating-a-memory-dump-in-csharp/

Using JsonPath with System.Text.Json to query JSON in .NETMeziantou's blog | Gérald Barré | September 21, 2026When you need to extract values from complex JSON payloads, manual navigation quickly becomes hard to read and maintain. Meziantou.Framework.JsonPath provides a JSONPath implementation for System.Text.Json based on RFC 9535, so you can query JSON documents using concise, standard expressions.https://www.meziantou.net/using-jsonpath-with-system-text-json-to-query-json-in-dotnet.htm🏷️ .NETAmazing .NET

Heartbeat: как мы создали систему управления системой вместо обычных сигналовХабр | 18 сентября 2026 г.Привет! Меня зовут Александр Илларионов, я бэкенд‑разработчик в Altenar. Мы работаем на довольно сложном и при этом очень интересном рынке: собираем данные о спортивных матчах со всего мира — например, время и место их проведения, описания чемпионатов и участников, а также вероятности наступления ключевых событий вроде голов, аутов и пенальти. И всё это в live‑режиме.В этой статье рассказываю, как мы переосмыслили роль Heartbeat‑компонента в нашей системе — от обычного сигнала до инструмента, который реально управляет работой всей системы. Наш опыт будет полезен тем, кто работает с .NET, распределёнными системами или строит инфраструктуру под высоконагруженные real‑time потоки данных.https://habr.com/ru/articles/1078782/🏷️ .NET, C#, Высоконагруженные системы, Микросервисы,Amazing .NET

If It Quacks - Part 2Steven Giesel | September 18, 2026Some days ago I wrote about duck-typing in C# with interceptors. Back then it was a proof-of-concept with a lot of rough edges. Now it is a real library: IfItQuacks.https://steven-giesel.com/blogPost/41599817-4457-441e-b874-1a5c67f4e7cc/if-it-quacks-part-2🏷️ .NET, C#

Build Your Own AI Agent Harness in C#, the MafClaw Live SeriesDevBlogs | .NET Blog | September 16, 2026A few weeks ago I wrote about going from dotnet run to a Foundry Hosted Agent in three lines of C#. The feedback was great. Developers liked the deployment story, the managed infrastructure, and especially the part where we did not spend the afternoon writing a Dockerfile, a session store, a telemetry pipeline, and a small distributed system just to expose one agent 😅.But that post starts near the end of the journey. It assumes you already have an agent worth deploying.So the next question is:https://devblogs.microsoft.com/dotnet/build-your-own-ai-agent-harness-in-csharp-the-maf-claw-live-series/

AI Is Changing How We Code. It’s Also Changing How We Learn.DevBlogs | Visual Studio Blog | September 16, 2026AI is changing software development at a pace no one can ignore.Developers now have powerful AI tools that can help us write code, understand unfamiliar codebases, troubleshoot problems, learn new frameworks, and get answers in seconds. That is an incredible opportunity. But as these tools become more capable, I believe something else is becoming more valuable too: learning directly from other developers.That’s one of the reasons I continue to believe so strongly in events like VSLive!.https://devblogs.microsoft.com/visualstudio/ai-is-changing-how-we-code-its-also-changing-how-we-learn/

Avoid API Breaking ChangesCodeOpinion | Derek Comartin | September 15, 2026Have you ever changed your backing data model and then all of a sudden all your clients explode?It’s not because you broke your code. You broke your contract.Most times API breaking changes occur because you’re exposing your domain model or data model. You’re not just sharing data. You’re leaking implementation details.https://codeopinion.com/avoid-api-breaking-changes/

А чё, так можно было? Три недооценённых атрибута.NETХабр | 14 сентября 2026 г.Три атрибута, которые меняют результат компиляции. Один запускает метод раньше Main. Второй передаёт текст выражения вместо результата. Третий ускоряет stackalloc в 50 раз.Все три описаны в документации и применяются внутри .NET. А в рабочем коде я их ни разу не видел.https://habr.com/ru/articles/1082206/🏷️ .NET, C#, ПрограммированиеAmazing .NET

Performance Improvements in .NET 11DevBlogs | .NET Blog | September 15, 2026Before television shows like The Office and Parks and Recreation cemented the mockumentary in the minds of millions, there was Christopher Guest. He didn’t invent the genre, but he’s widely recognized as one of its most influential practitioners, and for my money, there’s none better. I’ve watched Waiting for Guffman and Best in Show more times than I can count. But the one that has stuck with me the most, the one I quote at the slightest provocation, is This Is Spinal Tap.https://devblogs.microsoft.com/dotnet/performance-improvements-in-net-11/

XPath for custom types in .NETMeziantou's blog | Gérald Barré | September 14, 2026XPath is widely known as the query language for XML documents. Most .NET developers associate it with XPathNavigator, XmlDocument, or XDocument.
