"Monaco," Microsoft's browser-based Visual Studio dev environment, isn't the only codenamed technology that Microsoft demonstrated during its Visual Studio 2013 launch in New York.
Microsoft execs also showed off - without using the codename - a new technology in development for compiling directly .Net code to native code. That technology, from what I've heard from my sources, is codenamed "Project N."
Microsoft Project Manager Orville McDonald showed a quick demonstration during the Visual Studio launch of two different versions of Microsoft's FreshPaint app running on Microsoft Surface tablets. One of the versions made use of unspecified optimization technology that caused the application launch and run more quickly than the version without.
