Automatic differentiation library on Roslyn CTP?

Question

.NET

AD ( www.autodiff.org ) is a popular trend in high-tech programming.
Judging by my search, the solutions available for .net are either paid or
under .net 4.5 , which I would not like to depend on yet.
I personally need a simple library based on operator overloading and under net 3.5.
Based on the fact that the basis will be the known rules for differentiating binary operands and standard mathematical functions, as well as the rule for differentiating a complex function, then, at first glance, all this can be implemented on the basis of Roslyn CTP.
If anyone has dug in this direction or is interested in making such an open source package, please let me know.
For a term paper / diploma theme, it will also fit.

Answer 1

I almost finalized my system for differentiating, simplifying and compiling mathematical expressions under .NET and almost completed an article on Habr (in my opinion, it’s quite interesting and new), but my hands still don’t reach. If you're interested, I'd be happy to talk to you about it.
