用于Unity 3.0的Microsoft Unity Bootstrapper在这一行上引发了错误：
FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));
出现以下错误：
发生了'System.ArrayTypeMismatchException'类型的异常 mscorlib.dll但未在用户代码中处理
其他信息：尝试将元素作为类型进行访问 与数组不兼容。
整个代码都在这里，这是由nuget下载的bootstrapper预先制作和编写的。

更新解决方案
好的，这非常棘手。我不知道你是如何设法得到这种类型的项目的。您可能已从早期版本的ASP.NET MVC升级了项目类型。以下任何方式都是答案。
在Web.Config的运行时程序集绑定部分中，请添加以下内容。
<dependentAssembly>
<assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
<bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>
这可以解决您的问题。
