What stack/programming language is Azure written in?

Question

I am very impressed with the Azure dashboard UI and I can't figure out what stack/languages/etc it's made with? It works in all browsers, can copy/paste in all browsers and knows connection state. It does not look like Flash or Silverlight... or is it? Please help me figure this out.

Answer 1

The Azure portal is written in TypeScript and uses jQuery, KnockoutJS, Q, RequireJS, and Less (among a few other libraries). There's a thin ASP.NET Web API layer on the back-end, but most calls go directly to back-end services, like Azure Resource Manager (ARM).
