Tuning the default logging providers in ASP.NET Core through configuration https://bartwullems.blogspot.com/2026/10/tuning-default-logging-providers-in.html

For years, APIs have had one primary audience: applications. A frontend calls an endpoint, receives a response, and the developer handles whatever happens next. All of it was from a human user. Now, we have a new player: AI. Instead of simply following predefined application logic, an agent can decide which endpoints to call, determine the order of operations, retry failed requests, and carry out multi-step tasks based on a user's goal. Your API is no longer just serving an application, it may be serving an AI system capable of taking action. Companies like Stripe, Twilio, and Shopify have already launched dedicated Model Context Protocol servers to capture agent-driven traffic. https://blog.elmah.io/designing-apis-for-ai-agents-your-api-has-a-new-user/

NET 11 is presented as a release that “turns performance up to eleven,” delivering hundreds of targeted optimizations across the runtime, JIT, GC, async infrastructure, and core libraries. The article highlights major advances such as deeper devirtualization, smarter inlining, expanded escape analysis, leaner delegate structures, and a redesigned async/await system driven by the JIT rather than the compiler. Together, these improvements reduce allocations, shrink call overhead, streamline async state machines, and unlock faster execution paths—resulting in noticeably better real‑world performance without requiring developers to change their code. https://devblogs.microsoft.com/dotnet/performance-improvements-in-net-11/

If your .NET pods are each using 1–2 GB of RAM, you may be leaving a lot of pod density — and money — on the table. Here are the first things I would look at. https://ardalis.com/top-10-ways-to-reduce-net-memory-usage-in-kubernetes/

In real-world applications, duplicate API requests are more common than many developers expect. Users double-click buttons, mobile apps retry requests automatically, networks fail and resend calls, and background jobs may retry failed operations. https://medium.com/stackademic/how-to-prevent-duplicate-api-requests-in-net-c54e4770da2d

Create containers in .NET without Dockerfile? Here is how: Containers become the easiest way to distribute and run applications and services in the cloud. .NET app containerization could not be done without Dockerfile where multi-stage build steps. But, starting from .NET 7, this process is simplified. It strips down that pre-configuration by introducing built-in container support with the dotnet publish command. Before running a command you need to add the Microsoft.NET.Build.Containers package that will infer some of the project properties like base image, version, image repository, etc. For now, only Linux containers are supported.

OpenTelemetry in Microservice Architecture with .NET 9 What us OpenTelemetry and wht you need it? OpenTelemetry is the CNCF's vendor-neutral observability framework that unifies metrics, traces, and logs in distributed systems. .NET9 significantly improves OpenTelemetry support with built-in instrumentation, minimal configuration, and 35% reduced overhead compared to previous versions. https://medium.com/@serkutyildirim/opentelemetry-usage-in-microservice-architecture-with-net-9-16c2e57df59c
