解决方案

当你切换你的项目从MVC3到MVC4忘记改变System.Web.WebPages.Razor，版本= 1.0.0.0来出现同样的错误System.Web.WebPages.Razor，版本= 2.0.0.0，在web.config中。

I have installed vs2012 (11.0.50727.1),
I opened a new MVC4 with .NET 4.5 solution,
i create a simple HomeController and as I've wanted to start it locally, i have received this very strange error:
How can resolve it? What is this error and why it's happens???

Thank you in advance, for any of your help.

解决方案

The same error appears when you switch you project from MVC3 to MVC4 and forget to change "System.Web.WebPages.Razor, Version=1.0.0.0" to "System.Web.WebPages.Razor, Version=2.0.0.0" in the web.config.
