I mostly write code in C#. Though, recently I'm getting more and more attracted to functional programming and F#. I've learned a lot from F# for fun and profit, can highly recommend it.
Also, a big fan of Fabulous adventures in coding and Jon Skeet's coding blog
I find these posts on How to ask a question How to create a Minimal, Complete, and Verifiable example quite helpful and recently tend to link to them quite a lot. Adding it here to spread it by yet another mean of communication.
