>>Sorry Viv, I don't understand what you mean by "better suited to returning serialized data etc.". I use WebAPI with MVC, that is right and happy with it as much as one can be using .Net technologies. Actually, I am moving by API into Go for a much better experience (if better meant much faster, really works on multiple platforms etc:).

It is an open source language from Google, version 1 released in 2009. It is cross platform (you can write and compile the same code into native executable from and\or for multiple operating systems). I was and still writing with VFP and C#, but trying to learn it also for sometime. It looks better than others to me. You can check here and also try online without installing anything (UT also has a Go section since yesterday):

(Dropbox, docker ... all built with Go)
