Every couple of years someone declares .NET dead, and every couple of years it quietly ships another release that's faster than the last. In 2026 I still reach for C# on enterprise-shaped problems, and not out of nostalgia.

Boring is a feature

The clients who pick .NET are picking a decade of LTS releases, a debugger that works, and a hiring pool that doesn't evaporate when a framework falls out of fashion. "Boring" here means I can still run this in five years — which for a b2b system is the entire point.

Where it genuinely wins

• Throughput per watt. Modern .NET is shockingly fast, and the AOT story keeps improving.
• Tooling. Roslyn analyzers catch whole categories of bug before they reach review.
• Azure-shaped deployments. When the rest of the org already lives there, fighting it is a tax you pay forever.

I write plenty of Python — it's my day-to-day. But when a client says "this has to still be here, and still be supportable, in 2031," I'm reaching for C# and not apologising for it.
