I made a web site using VS 2012 and MVC4, it is work my localhost but when i published and put my host it doesn\'t work. IIS confiurations are same. But it gives me this err
I had similar issue installing nopCommerce 2.80 on server.
I use IIS7 net. 4.0 integrated pool. And just installed .net 4.5 from WebMatrix Products->Frameworks section. Restart will be required.
Then it started to work.
