As a developer, I take lot of screenshots and its time consuming to press the screenshot button, paste it in MSPaint or any other Image editing software and then save it.

And when you get, or post to, a URL, you inevitably involve the browser and get a full-page refresh. As I’ve explored it more, and as the facts have largely shown, my first impression was dead wrong. AJAX is definitely possible in ASP.NET MVC.

I remember when I started working on this particular project a few months ago. When I looked over the code for the first time, I noticed something funny about the cs files. Each cs file contained multiple public types. In the extreme cases, there were dozens of public classes in one file.
