我在 VS 2010 中使用 MVC4。我有一个异步操作，我正在尝试开始工作。我的控制器继承自 AsyncController 并且我有 ~Async 和 ~Completed 方法。我能够在示例测试项目中正确执行我的异步操作。但是当我将它作为我的核心网络应用程序的一部分运行时，它会出现此异常
[InvalidOperationException：无法同步执行异步操作方法“Complete”。] System.Web.Mvc.Async.AsyncActionDescriptor.Execute(ControllerContext controllerContext, IDictionary 2 parameters) +133
System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary2 参数) +39
我正在使用 Unity 进行依赖注入、ActionAttributeFilters 和 MVCSiteMapProvider，我想知道其中之一是否会导致上述问题。任何帮助表示赞赏。
谢谢
