MEFContrib.MVC3：导出带有基类的控制器
我在 CodePlex 上提出了一个问题，但尚未收到任何回复。
基本上，我有一个所有控制器都继承自的基本控制器。当我创建一个新的 MVC3 项目，将控制器放入另一个程序集中，并将 MEFContrib.MVC3 添加到该项目时，一切都运行良好。当我使任何控制器继承自我的基类时，它们将不再被发现。
我对 MEFContrib 不太熟悉，不知道到底出了什么问题，但我尝试用 ExportAttribute 装饰我的控制器，但这也没有奏效。
所有这些都是与主 MVC 项目不同的程序集：
public class MyBaseController : Controller
{
...
}
// This controller cannot be found.
public class HomeController : MyBaseController
{
public ActionResult Index ()
{
// Do Stuff
return View ();
}
}
// This controller can be found.
public class HomeController : Controller
{
// yada, yada, yada...
}
编辑：
coachlorben 是完全正确的。我的依赖项未正确标记为导出，因此无法正确组合控制器。我逐步检查了每个依赖项，逐步检查了它们自己的依赖项，并找到了一些我错过的项。
I have opened up a question on CodePlex but have not received any responses at all.
Basically, I have a base controller that all of my controllers inherit from. When I create a new MVC3 project, put my controllers in another assembly, and add MEFContrib.MVC3 to the project, everything works great. When I make any of the controllers inherit from my base class, they can no longer be found.
I am not familiar enough with MEFContrib to know what exactly is breaking, but I have tried to decorate my controllers with ExportAttributes and that has not worked, either.
All of this is a different assembly than the main MVC project:
public class MyBaseController : Controller
{
...
}
// This controller cannot be found.
public class HomeController : MyBaseController
{
public ActionResult Index ()
{
// Do Stuff
return View ();
}
}
// This controller can be found.
public class HomeController : Controller
{
// yada, yada, yada...
}
Edit:
counsellorben was exactly right. I had dependencies that were not properly marked for export and so the controllers could not be properly composed. I stepped through each of my dependencies, stepping through their own dependencies, and found the few I missed.

最可能的问题是
MyController类中的依赖项存在问题。这将导致任何继承自 MyController 的控制器出现问题。请参阅此答案，获取一些示例代码，您可以使用它来尝试诊断问题所在谎言。
The most likely issue is that there is a problem with a dependency in your
MyControllerclass. This will cause a problem with any controller inheriting from MyController.Please see this answer for some sample code you can use to try and diagnose where your problem lies.
我认为您需要用
InheritedExport属性进行装饰。I think you need to decorate with the
InheritedExportattribute.
