源错误：

我已经安装了MVC 3塞雷尔语和我的电脑上。我曾尝试与15日龄codeBase的，但同样的问题，取代它存在了。

I have installed MVC 3 on serer and on my computer. I have tried with replacing it with 15 days old codebase but the same problem exist.

现在我要解决它。难道有人知道我怎么能解决这个问题。

now I want to solve it. Do someone know how I can fix it.

推荐答案

在根Web.config确保assemblyBinding包含正确的版本为大会System.Web.WebPages.Razor和System.Web.Mvc 。检查他们的实际存在，以及我的System.Web.WebPages.Razor集结号标签缺失导致错误。我有我的程序集版本在写这篇文章以饱满的NuGet更新的时间分别为3.0和5.0。 code看起来应该像下面。该公钥将保持版本之间的相同。干杯！

In the root Web.config make sure assemblyBinding contains the proper version for the assembly "System.Web.WebPages.Razor" and "System.Web.Mvc". Check for their actual existence as well as my "System.Web.WebPages.Razor" assembly tag was missing causing the error. I had my assembly versions set to 3.0 and 5.0 respectively in the time of this writing with full NuGet updates. Code should look something like below. The publicKeyToken will stay the same between the versions. Cheers!

<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <!--some more bidings-->
  <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>

  <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
