C# patterns, AI, and EF Core tips
Issue #211 mixes C# design patterns, VS Code AI, EF Core pagination, Azure OpenAI, security, SQL Server locks, and MAUI migration advice.
Jasen's top three picks
- 1 Singleton Design Pattern in C#/.NET
victormagalhaes-dev.medium.com
A solid refresher on the Singleton pattern, with enough .NET framing to keep the classic example relevant.
- 2 AI and Remote Development in VS Code
youtube.com
A practical look at how AI fits into remote development workflows in VS Code, especially for distributed teams.
- 3 C# Delegates and Events: Powering Flexible Callbacks

Delegates and events get a clear treatment here, which is always useful when you need flexible callback wiring.
Editor's note
I pulled together a deliberately mixed lineup this week: classic C# patterns sit next to AI tooling in VS Code and practical data-access pieces. The EF Core pagination guide and the SQL Server lock article stood out because they solve problems people hit in real projects, not just theory.
