C# 14's extension member syntax now covers properties and static members, not just methods, yet a type's own member still silently wins over an identically named extension member. The author reproduces this against the .NET 10 SDK with eight tests: the build reports zero warnings and zero errors while every call site quietly switches to new logic.
A tutorial that wires .NET 10 into Pinecone, the managed vector database, using HttpClient and the REST data-plane endpoints instead of the archived C# SDK. It covers options binding, DI registration, upsert and similarity query, plus validation that keeps embeddings consistent.
Microsoft Agent Framework lets .NET developers turn a console app into an AI agent that can call tools with only a few lines of code. The article walks through creating the agent, wiring C# functions as tools, testing it locally, and moving the same code to production on Microsoft Foundry Hosted Agents.
The model's failure on the "strawberry" question isn't a counting problem: it never sees letters, only numeric pieces called tokens. Using Microsoft.ML.Tokenizers 2.0.1 and the gpt-5 tokenizer, the author measures this from C# and shows that the word alone is a single token with ID 101830, so the r's inside it stay out of reach. The piece also covers how token cost varies by language, by numbers, and by random text such as GUIDs, plus how to count tokens in .NET.
TermForge is a local web application built with .NET and React that merges SSH sessions, file browser, and Docker management into one unified tool. This project offers a modern solution to the challenges faced when switching between terminals and remote file systems across multiple servers.
Microsoft retires .NET 8 and .NET 9 on November 10, 2026, leaving apps without security patches unless they move to .NET 10. A new deployment-first checklist shows how to inventory what is actually running, retarget with minimal risk and prove the migration with artifact-level testing and a rollback rehearsal.
EF Core 11 lets the dotnet ef command-line tool read default options from a .config/dotnet-ef.json file. When your DbContext lives outside the startup project, you no longer need to repeat --project and --startup-project on every migration or database command. The tool finds the nearest config by walking up the folder tree, and explicit command-line flags still take precedence.
