⚡️ Rx.NET 7.0 released The endjin team has released Rx.NET 7.0 (the `System.Reactive` 7.0.0 package on NuGet). The key change resolves a long-standing assembly "bloat" problem: previously, adding an Rx.NET reference in self-contained apps with Windows target frameworks pulled in WPF and Windows Forms, inflating output by roughly 90MB (47MB with trimming, 11MB for NativeAOT). UI framework functionality now lives in separate packages — `System.Reactive.Windows.Forms`, `System.Reactive.Wpf`, `System.Reactive.WindowsRuntime`, and `System.Reactive.Uwp`. Support for .NET 7.0 and earlier has been dropped; target platforms are .NET 8, 9, 10, .NET Framework 4.7.2, and UWP. The release wraps up the technical-debt cleanup, clearing the way for performance improvements and new operators. ♻️ Subscribe for free now!

⚡️ Microsoft releases QDK 1.30 with faster quantum program compilation Microsoft has released version 1.30 of the Quantum Development Kit (QDK) — a platform for building quantum programs that compiles code from Q#, OpenQASM, and Qiskit into the industry-standard QIR format. The main addition is expanded capabilities for the Adaptive profile: expressing loops directly without unrolling, calling functions without inlining, and supporting unbounded loops such as "repeat-until-success." In some cases this cuts compilation time and program size by orders of magnitude. The release also adds new editor quick-fixes (auto-import and converting qubits to arrays) and configurable qubit-loss policies in noise models for two-qubit gates. In total, the release includes more than 40 merged pull requests with improvements to QIR generation, Stim compiler support, and the type system. ♻️ Subscribe for free now!

⚡️ Mistral AI strikes multibillion-dollar deal with Microsoft to expand Azure in Europe French startup Mistral AI — one of Europe's leading AI developers, known for its open-weight large language models and seen as the continent's main alternative to OpenAI — has announced a multibillion-dollar partnership with Microsoft to expand computing infrastructure across Europe (no specific figure was disclosed). The deal integrates Mistral's models into the Azure Foundry service and gives Azure customers access to the startup's France-based data centers. Two models are being added to Foundry — Mistral Medium 3.5 (open weights) and OCR 4 for document processing — with deployment options including Azure Local environments to meet data residency requirements. Microsoft President Brad Smith said the deal combines American and European technology. The partnership aligns with Europe's push for "sovereign AI." ♻️ Subscribe for free now!

⚡️ Background tasks in ASP.NET Core with NCronJob and SignalR Damien Bowden shows how to implement a background task scheduler in ASP.NET Core using the open-source NCronJob package together with SignalR to push execution status to clients in real time. Jobs implement the `IJob` interface with a `RunAsync` method that runs on a schedule and supports dependency injection — access to logging and SignalR hubs. In the example, two job types dispatch begin and end messages every five seconds, demonstrating concurrent and non-concurrent execution (the `[SupportsConcurrency(5)]` attribute), while the frontend displays these messages in real time via the SignalR JavaScript client. According to the author, the approach covers most typical scheduling scenarios while staying simple and maintainable. ♻️ Subscribe for free now!

⚡️ .NET 11 Preview 5: new Process APIs eliminate deadlocks when reading process output In the latest part of his .NET 11 preview series, Andrew Lock walks through the Process API improvements in Preview 5. The old approach with `StandardOutput.ReadToEnd()` and `StandardError.ReadToEnd()` could deadlock when reading a child process's output. .NET 11 adds safe methods that read stdout and stderr simultaneously: `ReadAllText()` / `ReadAllTextAsync()`, a line-by-line `ReadAllLines()` with `await foreach` support for real-time processing, `ReadAllBytes()` for raw data, and one-call `RunAndCaptureText()` methods that combine startup, output capture, and waiting for exit. The changes remove common pitfalls, cut boilerplate, and make the APIs more discoverable through modern C# constructs. ♻️ Subscribe for free now!

🎥 A Microsoft lecture on the engineering path to a utility-scale quantum computer Microsoft has published a lecture from its educational series "Building the Modern Quantum Architecture," devoted to the engineering path toward a utility-scale quantum computer — one capable of solving problems classical machines cannot touch. The presenter, Microsoft Technical Fellow Dr. Matthias Troyer, explains why the most promising applications lie in chemistry and materials science — from better batteries to sustainable coolants — and how quantum computing will work alongside AI and high-performance computing (HPC) to accelerate scientific discovery. He also explores the idea of teaching AI the laws of quantum physics to predict material properties more accurately. ♻️ Subscribe for free now!

⚡️ Brain: the AI system that flags Azure outages Microsoft has unveiled Brain, an internal AI-based system that continuously monitors Azure's health and increasingly acts on its own: declaring outages, halting problematic rollouts, and notifying affected customers. As Azure CTO Mark Russinovich explained, Brain builds a real-time digital twin of the cloud and assesses service health using machine learning. Automatic notifications have markedly cut support tickets, as customers learn about a problem before they need to call. On top of Brain, the company is already running AI agents that help find and fix the cause of an outage faster. ♻️ Subscribe for free now!

⚡️ Microsoft brings a .NET modernization agent to GitHub Copilot Microsoft has introduced the Upgrade Agent, a GitHub Copilot agent that automates migrating .NET applications to newer versions of the platform. Rather than a one-shot prompt, it runs as a multi-phase workflow: it assesses the project and its dependencies, builds a prioritized upgrade plan, executes code transformations, and tracks builds and errors in real time. Progress and code changes are shown on an interactive upgrade canvas. The agent is available in Visual Studio, Visual Studio Code, and GitHub Copilot CLI, and is added via the microsoft/upgrade-agent-plugins marketplace plugin. ♻️ Subscribe for free now!

⚡️ .NET CLI tools in the AI fury or how to guide agents during production investigations Christophe Nasarre discusses how to integrate diagnostic tools like dotnet-dump, dotnet-counters, and dotnet-dstrings with AI agents like Cursor, GitHub Copilot, Claude Code, and Visual Studio. In the article, the author describes three scenarios: turning your own CLI utilities into MCP servers with typed tools and ready-made workflows, using SKILL.md files to manage existing console utilities without changing their code, and a more advanced option — managing graphical applications like Windbg through a special bridge. According to Christoph, this approach allows AI to be entrusted not only with writing code, but also with a full-fledged investigation of problems in production, from finding memory leaks to analyzing locks and the causes of high application latency. ♻️ Subscribe for free now!

⚡️ Claude Code против Codex MCP. Directory has published a detailed comparison of two of the most popular agent-based CLIs for programming — Claude Code by Anthropic and Codex by OpenAI. The authors conclude that there is no overall winner between them: both tools support MCP, can independently edit code, work with Git, run commands, and use subagents. The key factors of choice are the model on which the agent works and the subscription already paid by the user. At the same time, the scenario of using both CLI simultaneously is becoming more and more popular among experienced developers: one agent writes code, and the other independently checks changes before committing. ♻️ Subscribe for free now!
