由调用lazyinitializer的目标抛出异常mvc4

Question

我想构建asp.net mvc4应用程序，并在运行应用程序时，我得到了关于lazyinitializer语句的错误Exception has been thrown by the target of invocation。请帮忙。提前致谢。我的代码如下

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，因为LazyInitializer在webconfig.just被模仿中删除该代码将运行良好
