VS 2012 generate .cs file from Json Schema file .json

Hi,

Please help me!!

I have Visual Studio Express 2012 for web in my machine, I want to generate .cs file from Json Schema file (.json extension).  

I am unable to install Web Essentials 2012 on top of Visual Studio Express 2012 for web. http://visualstudiogallery.msdn.microsoft.com/07d54d12-7133-4e15-becb-6f451ea3bea6

When I googled for any way to convert Json Schema into C# Classes, I came to know that Web Essentials 2012 has option to convert into .cs files.  

Thanks,

Areef
