運行我在Visual Studio中創建一個asp.net mvc4 Web應用程序工作正常。默認情況下，它會創建一個文件Filters\InitializeSimpleMembershipAttribute.cs。當這個屬性被調用時我正在上線34個例外：asp.net的MVC：InitializeSimpleMembershipAttribute拋出異常，當應用程序從IIS中運行，但當應用程序是從Visual Studio
using (var context = new UsersContext())
{
**if (!context.Database.Exists())**
{
// Create the SimpleMembership database without Entity Framework migration schema
((IObjectContextAdapter)context).ObjectContext.CreateDatabase();
}
}
唯一的例外發生在我嘗試運行通過IIS web應用程序，但運行通過Visual Studio F5或Ctrl + F5應用程序時不會發生（VS使用iisexpress我認爲）。 ConnectionString在兩種情況下都是相同的，並在下面複製。此外，我已將IIS中的應用程序池配置爲以我的身份運行（以匹配應用程序通過VS運行時發生的情況）。

我怎樣才能解決這個例外？異常的詳細信息，以防有人想：
