这里是堆栈跟踪

   at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly,    Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck)
   at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache)
   at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipVisibilityChecks, Boolean skipCheckThis, Boolean fillCache)
   at System.Activator.CreateInstance(Type type, Boolean nonPublic)
   at System.Activator.CreateInstance(Type type)

推荐答案

这是一个由于权限的问题。 IIS_User不是有访问权限的创建实例。

It was an Issue due to Permission. IIS_User was not having permission to Access to Create Instance.

更新管理员凭据到应用程序池和问题得到解决。

Updated Administrator Credential to App Pool and Problem was resolved.
