I probably would play around with it. During one layoff period I built a soduku solver. I'm disappointed in performance, (two minutes to find the same three results I had come up with by hand in a lot more time.) but also not surprised because of the IO needed. I suspect it would take much less time in C# because you can do customized eliminations. (pick the numbers with the least degrees of freedom first, then do the same with the new set, etc.) C# would be much better as a designer.
