Editor's note
I kept this issue intentionally mixed: there’s practical EF Core tuning, some fundamentals like testing and HTTP usage, and a few forward-looking pieces on .NET 10 and C# 13. The Visual Studio multi-process CPU analysis post stands out for day-to-day diagnostics, while the MCP server article is a good snapshot of where C# and AI tooling are heading.
