MT4 + DLL

Hi,

What programming language is the best choice for creating a DLL file for MT4?

According to this: https://stackoverflow.com/questions/3921541/programming-language-for-creating-dll-c-or-c-sharp

The goal is to implement machine learning strategy. I think it would be hard to use mql4 for everything in such scenario, thus I was thinking of using dll for ML output calculation, and trading / input data collection would be handled by MT4.

Other option is to use a bridge (ZeroMQ) but I think it could be a problem to run backtests (not sure).
