Idk how else to contact you: would you be interesting in solving another challenge?

C# is slower than Java here. Here is the currently fastest C# solution: https://github.com/PlummersSoftwareLLC/Primes/tree/drag-race/PrimeCSharp/solution_4

I'd think about it, but probably not right away at least. Just curious, what piqued your interest in this one now? From the looks of it the video is over a year old and the entries are many years old. You mentioned C# being slower than Java but I'm not certain what counts as the leaderboard? Looking at this link: https://plummerssoftwarellc.github.io/PrimeView/report?id=5406&hi=False&hf=False&hp=False&fi=&fp=mt&fa=wh~ot&ff=uf&fb=uk~ot&tp=False&sc=pp&sd=True shows a C# entry at 14th and Java at 41.

Are you interested in making a faster C# entry? I took a quick look and as best I can tell it seemed like the entries that do the best are probably the ones that get closest to clearing one prime multiple every assembly instruction. The top entries looked like they used source generation techniques to write unrolled loops to do long sequences of or operations against constant masks that could be embedded as immediate operands. I don't see any reason you couldn't do the same thing with a source generator for C#.
