并排安装错误MVC 4 Beta版侧 [英] MVC 4 Beta side by side installation error

问题描述

我刚安装的MVC 4 Beta版现在我的MVC 3应用程序不与下面的错误编译：

I just installed the MVC 4 Beta now my MVC 3 application does not compile with the following error:

该型'System.Web.Mvc.ModelClientValidationRule两个C：\\ Program Files文件（x86）的\\微软ASP.NET \\ ASP.NET MVC 3 \\组件\\ System.Web.Mvc.dll程序的存在和 C：\\ Program Files文件（x86）的\\微软ASP.NET \\ ASP.NET网页\\ 2.0 \\组件\\ System.Web.WebPages.dll'C：\\用户\\ michaeljo \\文件的\\ src \\ patientgive \\ Phc.Mvc \\基础设施\\ PasswordStrengthAttribute.cs

The type 'System.Web.Mvc.ModelClientValidationRule' exists in both 'c:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 3\Assemblies\System.Web.Mvc.dll' and 'c:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v2.0\Assemblies\System.Web.WebPages.dll' C:\Users\michaeljo\Documents\src\patientgive\Phc.Mvc\Infrastructure\PasswordStrengthAttribute.cs

这样看来这已被移动到不同的组件，并且自两个组件是在GAC它不知道使用哪一种。

It would appear this has been moved to a different assembly and since both assemblies are in the GAC it does not know which to use.

推荐答案

今天安装公测MVC4后，我的几个MVC 3的项目将不会编译。 （ModelClientValidationRule冲突）此修复程序是：

After installing MVC4 beta today, a few of my MVC 3 projects would not compile. (ModelClientValidationRule conflict) The fix was:

编辑：

ProjectName.csproj

修改

<Reference Include="System.Web.WebPages"/> 

要

<Reference Include="System.Web.WebPages, Version=1.0.0.0,
Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL "/>
