我的csproj有以下参考资料

<Reference Include="System.Data" />
<Reference Include="System.Data.Entity.Design" />
<Reference Include="System.Data.DataSetExtensions" />

web.config中

<system.web>
    <compilation debug="true" targetFramework="4.5">
      <assemblies>
        <add assembly="System.Data.Entity.Design,Version=4.0.0.0,PublicKeyToken=b77a5c561934e089" />
      </assemblies>
   </compilation
 </system.web>

这工作以前我需要一个新版本的System.Data.Entity.Design dll？或更改web.config中的程序集版本？

编辑：
Sounds like Identity Framework guys need to release a updated dll to match?
