无法加载文件或程序集“System.Web.WebPages.Razor，版本= 3.0.0.0 [英] Could not load file or assembly 'System.Web.WebPages.Razor, Version=3.0.0.0

问题描述

我想用外部登录，所以我用包管理器安装的Oauth：

  PM＆GT;安装封装Microsoft.AspNet.WebPages.OAuth
 

然后，我得到这个错误，安装完成后，然后我装剃刀：

  PM＆GT;安装封装Microsoft.AspNet.Razor
 

但我仍然有此异常。进一步我的应用程序是一个asp.net应用程序，而不是一个MVC应用程序。感谢您的帮助。

解决方案

您已经升级到剃刀3.请记住，VS 12（直到更新4）不支持它。安装剃刀从3或的NuGet通过这些步骤降级

I want using external logins so I installed Oauth by package manager:

 PM> Install-Package Microsoft.AspNet.WebPages.OAuth

Then I got this error after installed it then I install razor:

PM> Install-Package Microsoft.AspNet.Razor

But I still have this exception. Further more my application is an asp.net application and not a MVC application. Thanks for help.

解决方案

You have upgraded to Razor 3. Remember that VS 12 (until update 4) doesn't support it. Install The Razor 3 from nuget or downgrade it through these step
