C# shortcuts, performance, and .NET 10
A varied .NET roundup with C# ergonomics, performance tips, messaging architecture, DDD, observability, and .NET 10 preview coverage.
Jasen's top three picks
- 1 C# Made Simple: Skip the Project, Just Hit Run

The new dotnet run app.cs announcement is the kind of small DX change that lowers the barrier for newcomers.
Editor's note
I pulled together a pretty typical mixed bag this time: language tips, runtime/perf, architecture, and a few tooling and platform updates. I’d especially point you to the dotnet run app.cs announcement for the simplest entry point story, and the pattern matching and caching pieces for practical performance wins.
