asp.net-mvc – 汇编绑定重定向不工作

我试图在Azure上部署一个测试Web应用程序,但是当我在本地机器上运行Azure模拟器时,我会从附加到我的WebRole的Azure模拟器控制台得到这个错误：

System.TypeLoadException: Unable to load the role entry point due to the following     exceptions:

只要我在本地机器上安装了MVC3(MVC3程序集在GAC中),但是由于我删除了MVC3(Azure没有安装MVC),所以一直工作正常,我收到这个错误.我的网络应用程序经常包含MVC4,工作正常.我曾经想过装配绑定重定向,我注意到在我的web.config文件中我已经有：

<runtime>    
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">      
    ...
    <dependentAssembly>        
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" culture="neutral" />
      <bindingRedirect oldVersion="0.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
    </dependentAssembly>
    ...
  </assemblyBinding>
</runtime>

这应该是正确的,根据我在互联网上阅读的文件.我也尝试将System.Web.Mvc.dll(版本4.0.0.0)的SpecificVersion属性设置为false,但无效.我错过了什么吗？不应该将调用组件ActionMailer.Net.Mvc自动重定向到正确版本的MVC程序集？任何想法都非常感激.谢谢.

解决方法

这样做的一个副作用是您的RoleEntryPoint将无法访问您的web.config.

> Azure SDK 1.3 -1.7将查看WaIISHost.exe.config
> Azure SDK 1.8将查看WebRoleProjectName.dll.config.

随着SDK的最新更改,您应该可以在应用程序中放置一个app.config,然后角色入口点就可以访问它.
