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.
This article explains the difference between delegates and events in C#, the subscription boundary an event creates, and how multicast invocation behaves when a handler throws. It also covers what notification does not guarantee: completion of every subscriber, async handling and subscription lifetime. Read it to design event-based notifications with clearer contracts.
Nick Cosentino explains how to package a recurring .NET review job as a project-scoped Claude Code skill. The example reviews endpoint changes across validation, authorization, response mapping and persistence, and the article stresses clear limits on what the agent may run. It is a practical starting point for teams that want repeatable AI-assisted reviews of ASP.NET Core code.
A guide to how the MongoDB C# driver maps objects to BSON documents. It covers explicit element names, creator maps for immutable records, choosing the BSON _id type, and ignoring extra fields. It also argues that compatibility should be checked against stored fixtures, not only a fresh round trip.
How should you configure Claude Code permissions so a coding agent can build and test a .NET project without gaining database or publish authority? This guide explains the documented rule order, settings scopes, wildcard risks, and boundaries for migrations and deployments. It is worth reading before you run agents unattended on .NET repositories.
Claude-generated .NET tests can look complete and still miss the regression they are meant to catch. The author walks through tracing assertions back to their inputs, checking mock boundaries, and verifying that a test fails for the intended reason. It is a practical review checklist for anyone accepting agent-written tests into a C# codebase.
The article explains how to register MongoClient as a singleton in ASP.NET Core and how request-scoped services should borrow it. It shows that disposing the client through the container does not close the driver's cluster, and that the selected driver version changes the answer. It is a useful reference for teams running MongoDB in web apps.
Nick Cosentino explains how to set up C# code intelligence in Claude Code through the csharp-lsp plugin and where that setup stops being reliable. The article separates the language server, the plugin and the workspace as three layers to verify, and it clarifies what diagnostics and symbol navigation can and cannot prove. It is a practical checklist for .NET developers using Claude Code on C# repositories.
