Microsoft has unprecedented development support for the mobile web with Visual Studio 2012 and ASP.NET MVC 4.0. Out-of-the-box, the latest environment supports:
HTML5 and CSS3 (standards crucial to developing responsive mobile web apps)
The ability to merge, compress, and transform JavaScript and CSS files to minimize browser requests and bandwidth requirements
New convention support to target specific mobile platforms
As part of the new mobile application project template, jQuery Mobile integration into your mobile app projects
All of these improvements to Microsoft's development environment directly address the constraints with which we, as developers, engineers, architects, and content designers, must concern ourselves. If you couple these improvements with the improvements in .NET 4.5, .NET users such as us can now target the mobile web better than ever before.
