由調用lazyinitializer的目標拋出異常mvc4

Question

我想構建asp.net mvc4應用程序，並在運行應用程序時，我得到了關於lazyinitializer語句的錯誤Exception has been thrown by the target of invocation。請幫忙。提前致謝。我的代碼如下

namespace CMMIS.Web.Filters 
{ 
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)] 
public sealed class InitializeSimpleMembershipAttribute : ActionFilterAttribute 
{ 
    private static SimpleMembershipInitializer _initializer; 
    private static object _initializerLock = new object(); 
    private static bool _isInitialized; 

    public override void OnActionExecuting(ActionExecutingContext filterContext) 
    { 
     // Ensure ASP.NET Simple Membership is initialized only once per app start 
     LazyInitializer.EnsureInitialized(ref _initializer, ref _isInitialized, ref _initializerLock); 
    } 

Answer 1

它，因爲LazyInitializer在webconfig.just被模仿中刪除該代碼將運行良好
