ASP.NET MVC 4, el método "WebSecurity.InitializeDatabaseConnection" se puede llamar solo una vez
Estoy desarrollando una aplicación web de código primero en Visual Studio 2012 Express.
Yo uso esta cadena de conexión en el web.config:
<add name="myContext" connectionString="Data Source=.;Integrated Security=True;Initial Catalog=cityKingMVC4" providerName="System.Data.SqlClient" />
Estoy usando SimpleMembership.
Estoy tratando de sembrar 1 administrador de Filters / InitializeSimpleMembershipAttribute.cs: ...
WebSecurity.InitializeDatabaseConnection("myContext", "Users", "UserId", "Email", autoCreateTables: true);
// A: Create Admin user
if (!WebSecurity.ConfirmAccount("[email protected]"))
{
WebSecurity.CreateUserAndAccount("[email protected]", "password");
}
// B: Create admin role if not exist
if (!Roles.RoleExists("Administrator"))
{
Roles.CreateRole("Administrator");
Roles.AddUserToRole("[email protected]", "Administrator");
}
Si comento A & B no se bloquea. Si no obtengo esto: el método "WebSecurity.InitializeDatabaseConnection" solo puede llamarse una vez.
Si depuro y coloco un punto de interrupción en 'WebSecurity.InitializeDatabaseConnection', solo lo llama una vez y no hay otro código que llame a WebSecurity.InitializeDatabaseConnection en ningún lugar.
Si depuro, se bloquea en una línea diferente más arriba en el archivo (archivo SimpleAuthentication estándar): LazyInitializer.EnsureInitialized (ref _initializer, ref _isInitialized, ref _initializerLock);
con este error: el destino de una invocación ha generado una excepción.
Traza de la pila:
