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.
A method that returns IReadOnlyList<T> tells the caller it cannot write, but says nothing about whether the data is an independent copy, a live view or a fixed report. The article separates the declared capability from the ownership and lifetime contract, then evaluates each collection return shape against both layers.
A developer red-teamed the confirmation step of a refund MCP server built on ASP.NET Core with the official C# SDK (ModelContextProtocol 2.3.0). Six attacks — plain-JSON requestState, replaying another user's approval, injected form fields and a pre-checked consent box — each led to a concrete server-side defense, plus a checklist you can apply to your own tools.
A C# walkthrough of Gauss-Legendre quadrature that computes Legendre polynomial roots and weights at runtime instead of shipping precomputed tables. Bonnet's recurrence keeps the polynomial evaluation stable past degree 15, and Newton's method finds each root to about 1e-10 in a few iterations.
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.
FAIRouter, an open-source C# router that picks a language model per request and validates the reply with a judge model, is now published on NuGet as FAI.Router (0.1.0, .NET 10). A few lines of code connect OpenRouter or any OpenAI-compatible endpoint, score answers, collect feedback and train the router's weights.
The third post in a series looks at Caliburn.Micro's conventions: how the framework pairs a View with its ViewModel through naming rules and reflection. It walks through ViewLocator's two-step lookup, the five default regex rules in NameTransformer, and why AssemblySource determines whether a View can be found at all.
Saving a lead and then calling Odoo means two writes that can each fail on their own. Anas Amin describes a transactional outbox where the lead and a message describing it commit together, and a Hangfire job delivers the message later. Leased claims, error classification, dead-lettering and idempotent Odoo writes carry the rest of the design.
In SQL Server 2019 and later, varchar columns using a collation whose name ends in _UTF8 can store Unicode text, so not every text column has to become nvarchar. The change is more than a single database setting, though: comparisons, sorting, unique indexes and storage sizes all shift. The article lays out a step-by-step path from column inventory to production rollout.
