I think the issue has been solved, but if not, use this package from Nuget:

If you're using visual studio open the nuget packages windows and run Update-Package, this will update all your dll to the last version. If it still not work, see this page: http://www.asp.net/mvc/tutorials/mvc-5/how-to-upgrade-an-aspnet-mvc-4-and-web-api-project-to-aspnet-mvc-5-and-web-api-2

如果您正在使用visual studio打开nuget包窗口并运行update - package，这将把您的所有dll更新到最后一个版本。如果它仍然不工作，请参见此页:http://www.asp.net/mvc/tutorials/mvc/mvc/mvc/mvc -4和web-api- 5和web-api-2。

I had a similar problem, and solved it by based on the article Updating Razor 2.0 to 3.0 with Asp.net MVC by by Anthony Fassett

我遇到了一个类似的问题，并根据安东尼·法塞特(Anthony Fassett)的文章更新Razor 2.0到3.0的Asp.net MVC，解决了这个问题。

The following block of code was missing from my Web.Config:

我的Web.Config缺少以下代码块:

<dependentAssembly>
  <assemblyIdentity name="System.Web.WebPages.Razor" publicKeyToken="31bf3856ad364e35" />
  <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="3.0.0.0" />
</dependentAssembly>

There are multiple solutions for this problem:

这个问题有多种解决方案:

• Follow the tutorial on upgrading your asp.net solution
• 按照本教程来升级asp.net解决方案
• Don't forget to remove the Microsoft-Web-Helpers dll and install the nuget package Microsoft.AspNet.WebHelpers
• 不要忘记删除microsoft - web - helper dll并安装nuget包microsoft.aspnet . webhelper

Then, make sure you have upgraded all your nuget Packages (use "Upgrade-Package") and check your dll's in web.config.

然后，确保升级了所有nuget包(使用“升级包”)，并在web.config中检查dll。

The error is probably an action in an old DLL, when you are converting your project.

在转换项目时，错误可能是旧DLL中的一个操作。

In my case, a nuget installation had changed my Web.Config:

在我的例子中，nuget安装改变了我的Web.Config:

    <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.1.0.0" newVersion="1.1.0.0" />
  </dependentAssembly>

newVersion="1.1.0.0"** should be newVersion="5.1.0.0"

新版本= " 1.1.0.0 " * *应该是新版本=“5.1.0.0”

In my case it was an incompatibility issue. I had theses pacakges:

在我看来，这是一个不相容的问题。我有这些包:

• Microsoft.AspNet.Mvc version 4.x
• Microsoft.AspNet。Mvc版本4. x
• Microsoft.AspNet.Razor and Microsoft.AspNet.WebPages, version 3.x
• Microsoft.AspNet。剃刀和Microsoft.AspNet。网页,版本3. x

I suppose that upgrading Mvc to 5.x would have worked, but I needed to keep Mvc 4.x, so i had to downgrade Razor and Mvc to 2.x. To do so, you just have to install the older version, like this:

我想把Mvc升级到5。x可以工作，但是我需要保持Mvc 4。所以我不得不将Razor和Mvc降级为2。x。为此，您只需安装旧版本，如下所示:

Install-package Microsoft.AspNet.WebPages -version 2.0.30506
Install-Package Microsoft.AspNet.Razor -Version 2.0.30506

After downgrading these packages, the first error disappeared, but there was still another error related to a problem in web.config. I had to change the binding redirect for Razor:

在降级这些包之后，第一个错误消失了，但是还有一个错误与web.config中的问题有关。我必须为Razor更改绑定重定向:

<dependentAssembly>
     <assemblyIdentity name="System.Web.Razor" ... />
  <!--bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0" /-->
     <bindingRedirect oldVersion="0.0.0.0-2.0.0.0" newVersion="2.0.0.0" />
</dependentAssembly>

I don't know why, but the binding redirect wasn't updated by the Nuget installation, which should have done it.

我不知道为什么，但是绑定重定向不是由Nuget安装更新的，应该是Nuget安装更新的。

I received this error when I upgraded a NuGet package - 'Microsoft.AspNet.Web Pages' version 3.2.3. I am using VS2012, starting a new vanilla 'ASP.NET MVC 4 Web Application' with template 'Internet Application' using Windows Authentication or Windows Azure authentication.

Perhaps the update is not compatible with other components, and these other components must also be upgraded. Other answers suggest updating Microsoft.AspNet.Mvc, Microsoft.Net.Compilers, and/or Microsoft.AspNet.WebHelpers.

更新可能与其他组件不兼容，这些其他组件也必须进行升级。其他的回答建议更新微软。aspnet。Mvc,Microsoft.Net。编译器、和/或Microsoft.AspNet.WebHelpers。
