MVC异步错误 - 异步操作方法'Complete'不能同步执行

Question

我在VS 2010中使用了MVC4。我有一个异步操作，我尝试工作。我的控制器从AsyncController继承，我有〜异步和〜完成的方法。我能够在示例测试项目中正确执行我的异步操作。但是，当我运行它作为我的核心web应用程序的一部分，它让这个异常

[InvalidOperationException异常：异步操作方法“完全”不能同步执行] System.Web.Mvc.Async.AsyncActionDescriptor.Execute（ControllerContext控制器上下文，IDictionary 2 parameters) +133 System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary 2个参数）+39

我使用Unity的依赖注入，ActionAttributeFilters和MVCSiteMapProvider，我想知道如果其中之一是导致上述问题。任何帮助表示赞赏。

感谢

它看起来像NotFoundMVC库导致这个问题。卸载这个软件包，你会得到很好的工作！
