When I used Firefox 39.0 to download the update on Windows, I got the previous version, 0.3.0. I had to use Internet Explorer 11 to get the latest version, 0.5.0. (I didn't try Chrome.)
I've been using Visual Studio 2013 + Node Tools + Web Essentials to do all my Web and Node.js projects. Nothing beats it in my opinion. Being able to walk through Javascript easily without a bunch of complicated configs is super nice.<p>VS Code seems to do much less right now. I wonder if it will ever be as useful to me as the full IDE.
