I've been using Microsoft MVC for a few years now, so I was, of course interested in the new MVC 3 (released early 2011).
And what a surprise - there's a whole new language called Razor!
I can still use traditional "code-behind" files (.aspx), but I'm being encouraged to use Razor instead. At 1st glance, Razor looks a bit like Classic ASP, but in fact it's got more in common with Haml (or NHaml).
