asp.net-mvc - 使用HttpSelfHostServer和IDependencyResolver时的"Inheritance security rules violated"

我正在尝试使用HttpSelfHostServer自托管ASP.NET MVC 4 WebAPI。一切正常，我尝试添加自定义依赖项解析器。 (最终，这将使用StructureMap，但我什至还没有达到这一点)。如果尝试实例化自定义解析器，则在启动服务器时会收到以下异常:



代码如下:

public class CustomDependencyResolver : IDependencyResolver
{
    public object GetService( Type serviceType )
    {
        return null;
    }

    public IEnumerable<object> GetServices( Type serviceType )
    {
        return null;
    }
}

...

// To trigger the exception, all I need to do is instantiate the custom resolver.
var dependencyResolver = new CustomDependencyResolver();

// Exception is thrown when I create the server:
var server = new HttpSelfHostServer( _config );

请注意，我无需对解析器进行任何操作，这很简单，实例化该解析器的操作会在以后触发失败。

奇怪的是，此异常仅在调试(F5)中发生-如果我通过Ctrl + F5运行，则一切正常。

关于如何解决此问题有任何想法吗？

最佳答案

终于找到答案了；因此回答我自己的问题。

原来有两种IDependencyResolver:一种在System.Web.Http.Services中，另一种在System.Web.Mvc中。

两者都可以在非调试状态下编译和运行。
System.Web.Http.Services.IDependencyResolver 是正确的一个。
System.Web.Mvc.IDependencyResolver似乎会引起问题。
