Question

我们有一个使用T4MVC的大型.NET Web应用程序MVC3。我们最近将它升级到MVC4，除了T4MVCExtensions（来自NuGet的3.6.5版）仍然依赖于System.Web.Mvc版本3之外一切都很好。你应该在web.config中设置的运行时依赖项应该是什么重定向程序集绑定，但它们似乎不是。发生以下异常：

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，应该映射它，但它似乎不是 -

<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>

我已经启用了融合日志，只是为了真实地验证我的疯狂，并且看到了，确实，它似乎确实尝试使用mvc3二进制文件，而不是4：

任何想法都会摇摆不定，因为我已经烧了好几个小时。

Answer 1

在将一组MVC3项目手动升级到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中有汇编绑定元素，但我收到类似于T4MVC错误的错误，但来自Telerik MVC Extensions。

Fusion Log查看器很有用，因为它确认将两个版本的system.web.mvc加载到应用程序域中。

最后，从项目的根web.config中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>

删除命名空间后，它看起来像这样：

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

此博客文章提供了有关错误命名空间的更多信息： http://www.dotnetish.com/runtime/xmlnshttpschemas-microsoft-com-netconfigurationv2-0/

Answer 2

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，以查看它是否表现相似。 T4MVC辅助组件应该没有任何特殊之处。

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，它运行正常。它适合你吗？

如果所有其他方法都失败了，如果你可以共享一个repro项目（例如在github上），我可以尝试一下。

AssemblyBinding BindingRedirect不适用于带有T4MVCExtensions的MVC4应用程序
