什么曾经在我的asp.net webforms应用程序中工作现在抛出此错误:

System.MissingMethodException:找不到方法

该DoThis方法在同一个类上,它应该工作.

我有一个通用的处理程序:

public class MyHandler: IHttpHandler
{
    public void Processrequest(HttpContext context)
    {
      // throws error now System.MissingMethodException: Method not found?
      this.DoThis(); 
    }

    public void DoThis()
    {
    //
    }
}

在VS 2010中构建网站项目时,我遇到以下异常:

The pre-application start initialization method Run on type WebActivator.ActivationManager  threw an exception with the following error message: Exception has been thrown by the target of an invocation..     

我该如何调试呢？当我使用VS.NET和命令行(例如,通过NAnt/MSBuild)构建时,就会发生这种情况.

用于Unity 3.0的Microsoft Unity Bootstrapper在此行上引发错误:

FilterProviders.Providers.Add(new UnityFilterAttributeFilterProvider(container));

出现以下错误:

mscorlib.dll中出现"System.ArrayTypeMismatchException"类型的异常,但未在用户代码中处理

附加信息:尝试将元素作为与阵列不兼容的类型进行访问.

整个代码都在这里,这是由nuget下载的bootstrapper预先制作和编写的.
