Bending the Compiler: Writing C# Code That JIT Treats Differently
Every C# developer has felt it: the code that should be fast, but isn't. Or the ugly hack that flies. The JIT compiler in .NET is not a black box—it h...
Source Generator Design Strategies
What to Fix First When Your Generator Slows Down the Whole Solution
You ship a source generator. Next sprint, the assemble slows by forty percent. No new files changed. Just the existing generator, now doing more effor...
