Infragistics has made more than 50 of its Blazor controls free and open source under the MIT license, and its engineers are contributing directly to the framework. New .NET 11 analyzers from the collaboration are merged into ASP.NET Core, so every Blazor developer gets the tooling benefits, whether or not they use its components.
A beginner's guide to adding Serilog to Blazor applications. It covers file and console sinks for Blazor Server and the browser console or remote API approaches for Blazor WebAssembly. Useful for Blazor developers who need to choose a logging strategy that fits their hosting model.
Azure Cosmos DB Shell lets you browse databases, containers and items from the terminal. This walkthrough pairs the shell with the local Azure Cosmos DB Linux Emulator and the FleetCharge sample data to show connecting, navigating, querying and point reads. It is a practical way to check what your application actually stored during development, without opening the portal or adding diagnostic code.
JasperFx shipped a coordinated Critter Stack release wave: CritterWatch 1.1, Bobcat 1.0, AI Skills 1.17 and a Stoat 0.5.0 preview. CritterWatch's MCP server now exposes 83 tools, and Bobcat 1.0 turns existing test methods into executable specifications. Worth a look if you run Wolverine or Marten in production or write integration tests on the .NET stack.
The built-in terminal in JetBrains IDEs now runs on libghostty starting with version 2026.3, replacing the older JediTerm emulator. CLI agents such as Claude Code and Codex get modern keyboard protocols, automatic theme switching and far better rendering of terminal output. Developers who run agents inside the IDE will notice the difference right away.
The Microsoft Intune team used the GitHub Copilot modernization agent to move an enrollment service from .NET Framework 4.7.2 to .NET 8 while hosting it on AKS. The author reports cutting one library's migration from about six weeks to one and a half. The most useful part is the working method: an editable migration plan and progress file kept in the repository, and a clear account of where the agent failed on internal libraries.
Khalid Abuhakmeh compares every practical way to loop through a List<T> in C#, from foreach and for to List.ForEach, Index() and spans, and benchmarks them on .NET 10 and .NET 11 RC 1. The post also covers safe removal during iteration and async loops. It is a useful reference for choosing the right loop in everyday and hot-path code.
Assisted permissions are now generally available in GitHub Copilot CLI, the GitHub Copilot app and VS Code. A language model reviews each permission request, auto-approving those it judges clearly safe while sending the rest for your approval. Enterprises can control the mode through policy.
Uno Platform's Matt Mattei explains how he checks code that AI agents write for .NET and Uno Platform apps. He combines written specs, runtime checks, lint hooks and change-cost probes. The post gives working .NET developers a concrete review checklist for agent-written features.
Microsoft's PostgreSQL extension brings connecting, browsing schemas, writing and running SQL, and asking GitHub Copilot about the connected database into VS Code. The post walks through four workflows, from exploring a first table to reviewing a performance recommendation. It is a practical guide for .NET developers who work against PostgreSQL and want to stay in their editor.
PHP disclosed two critical vulnerabilities on October 21, 2026 that can allow remote code execution. Azure DevOps Services and Server do not use PHP for customer requests, so the exposure sits in the PHP runtimes your pipelines, agents, containers and deployed apps use. The post explains which PHP installs Microsoft patches and which ones you must patch.
Auto mode in Claude Code still lets an AI classifier decide which actions are safe. The author shows how to add ask and deny rules to a .NET project's settings file to keep control over EF Core migrations, running the app and database updates. He also explains that a deny rule wins over allow and ask rules, whichever settings file holds it.
