ausgelöst. Ich arbeite mit Entity Framework 6.1.3, ASP.NET Identity Entity Framework 2.2.1 und Oracle 12C in ein ASP.NET MVC5-Projekt.Der Typinitialisierer für 'System.Data.Entity.Migrations.DbMigrationsConfiguration`1' hat eine Ausnahme mit der Oracle-Datenbank
Während ich versuche, die Datenbank mit Nuget Befehl zu erzeugen: -
Enable-Migrations
Ich erhalte die unter Ausnahme

modelBuilder.Entity<IdentityUserLogin>().ToTable("UserLogins");
modelBuilder.Entity<IdentityUserClaim>().ToTable("UserClaims");
}
public static ApplicationDbContext Create()
{
return new ApplicationDbContext();
}
}
So ist meine Frage, wie diese Fehler zu lösen, und wenn ich falsch bin, wie mit Entity Framework arbeiten Code zuerst mit Oracle Datenbank?
Überprüfen Sie 'machine.config' Inhalte in% WinDir% \ Microsoft.NET \ Framework \% Version% \ Config \ machine.config. Wenn das Element "oracle.manageddataaccess.client" bereits vorhanden ist, sollten Sie wissen, dass Sie es zweimal deklarieren, während web.config während der Konfigurationslaufzeit der Datei machine.config beitritt. –
Dann können Sie nur eine von ihnen verwenden (nicht beide Abschnitte). Ich bin nicht sicher, ob Sie den gleichen Abschnitt in machine.config löschen können, aber Sie können versuchen, Abschnitt mit demselben Namen in web.config/configure machine.config zu entfernen, um den Oracle-Provider ohne web.config zu laden. –
@TetsuyaYamamoto Danke. Gelöst. – Ashiquzzaman
