解决“System.Web.Mvc.ModelClientValidationRule”冲突的问题

解决方法：

 

1、在 Web.Config 中   <appSettings> 节点增加如下节点

 

<add key= "WebPages:Version"   value= "1.0.0.0"/>

 

2、修改项目文件（*.csproj）中如下节点

 

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

 

修改为

 

<Reference Include= "System.Web.WebPages, Version=2.0.0.0,Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL "/>     <Reference Include= "System.Web.Helpers, Version=2.0.0.0,Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL"  />
