Yes - .NET 5 and 6 both have runtimes and SDKs available for Mac and Linux. At least in my opinion, Linux is the preferred deployment platform for it now unless you have a specific (usually older) library that only works on Windows.
> .NET 5 finally delivered Linux support but only eleven months ago
The previous versions in this stream (.NET Core 2.1, .NET Core 3.0 and 3.1) also run fine on Linux. For web server / API server workloads, it's been stable for a lot longer than 11 months, and people do indeed "bet the farm" or "run the business" on it, quite happily.
Technically, this starts with .NET core 2.1 on 2018-05-30. The prior version, 2.0, released on 2017-08-14, wasn't _quite_ there yet although some people were happy with it for production use.
.NET has been on Linux for years now. And my company is using it in production on Kubernetes (Linux/Debian). Its crazy how dependable and fast it is. Startup times are amazing and its only getting better each year. We're looking to upgrade to .NET 6 in production by January.
Have you even seen the benchmarks compared to Java and other languages?
I can also confirm that I’ve been using .NET on non Windows OSes for years and it works really well. However the Benchmarks are rigged. The code they wrote for that one benchmark for in the top is a complete cheat. Check out the source and compare it with the other ones from the top 10. .NET is fast but Java is truthfully still faster.
