AssemblyBinding BindingRedirect不适用于使用T4MVCExtensions的MVC4应用程序

Question

我们有一个大型的.NET web应用程序，它是使用T4MVC的MVC3。我们最近将它升级到了MVC4，除了T4MVCExtensions (来自NuGet的3.6.5版本)仍然依赖于System.Web.Mvc版本3之外，一切都很好。您应该在web.config中设置的运行时依赖项应该重定向程序集绑定，但它们似乎并非如此。出现以下异常：

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Description: An unhandled exception occurred during the execution of the current web     request. Please review the stack trace for more information about the error and where it originated in the code. 

Exception Details: System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

我们的web.config文件中有以下内容，它应该映射它，但它似乎没有-

<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
  <dependentAssembly>
    <assemblyIdentity name="System.Web.Helpers"
                      publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0" />
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc"
                      publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-3.0.0.0" newVersion="4.0.0.0" />
  </dependentAssembly>
  <dependentAssembly>
    <assemblyIdentity name="System.Web.WebPages"
                      publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0" />
  </dependentAssembly>
</assemblyBinding>

​

我启用了融合日志，只是为了验证我的疯狂程度，并且看到，是的，确实，它似乎确实在尝试使用mvc3二进制文件，而不是4：

任何想法都会很震撼，因为我已经在这上面花了好几个小时了。

Answer 1

在手动将一组MVC3项目升级到MVC4之后，我遇到了一个非常类似的程序集绑定问题。尽管在web.config中有程序集绑定元素，我还是收到了类似于T4MVC错误的错误，但是来自Telerik MVC扩展。

Fusion Log viewer非常有用，因为它确认两个版本的system.web.mvc正在加载到应用程序域中。

最后，从项目根web.config的根配置元素中删除命名空间解决了这个问题。

所以，web.config是这样的：

<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<!--... elements deleted for clarity ...-->
</configuration>

删除名称空间后，它看起来如下所示：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<!--... elements deleted for clarity ...-->
</configuration>

为了隔离，我会尝试创建一个针对MVC3构建的小型虚拟程序集，看看它的行为是否类似。T4MVC帮助器程序集不应该有任何特殊之处。

另外，请查看我的测试项目https://github.com/davidebbo/T4MVCSampleApp。这是一个使用最新T4MVC的MVC4项目，它对我来说运行得很好。它能为你运行吗？

如果其他方法都失败了，如果你可以分享一个repro项目(例如在github上)，我可以试着去看看。
