MathNet.Numerics has a pretty solid linear systems solver, and has multiple additional native providers that, depending on what hardware you have to work with, and the size of your solves, dramatically increases performance.

Yes! I actually had this exact desire years ago, and went searching for it. RegexBuddy does this, best $US 40 I’ve spent. It’ll even do its best to make something that’ll match the same things, even if you’re using features that aren’t technically supported in the target. Don’t worry, it’ll describe exactly what doesn’t work, and why, when it does that.
For example, if I ask it to convert from C#
/(?>atomic) case-(?i)insensitive(?-i) string/to JavaScript (chrome) it’ll throw out:/(?:atomic) case-[iI][nN][sS][eE][nN][sS][iI][tT][iI][vV][eE] string/, along with the warning:Conversion is incorrect because the target application's regular expression flavor doesn't have certain features: JavaScript (Chrome) does not support atomic grouping
