Exception System.Data.Entity.Core.ProviderIncompatible dans MVC 5

Je crée une application Web ASP.NET dans MVC5 et j'ai créé une classe de modèle avec un contrôleur. Mon application est en cours d'exécution, mais lorsque je souhaite accéder à mon contrôleur de films dans une URL telle que localhost: 1234/Movies, une exception est générée dans mon fichier MoviesController.cs.

La chaîne de connexion que j'utilise est 

<connectionStrings>
    <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\aspnet-MvcMovie-20130819083100.mdf;Initial Catalog=aspnet-MvcMovie-20130819083100;Integrated Security=True"
      providerName="System.Data.SqlClient" />
    <add name="MovieDBContext" connectionString="Data Source=(LocalDb)\v11.0;AttachDbFilename=|DataDirectory|\Movies.mdf;User ID=sa; Password=password@123;" providerName="System.Data.SqlClient"/>
</connectionStrings>

Fonction qui génère cette exception est

public ActionResult Index()
{
    return View(db.Movies.ToList());
}

Modifier les détails de l'exception

Une exception de type 'System.Data.Entity.Core.ProviderIncompatibleException' s'est produite dans EntityFramework.dll mais n'a pas été gérée dans le code utilisateur.

Informations complémentaires: Une erreur s'est produite lors de l'obtention des informations sur le fournisseur à partir de la base de données. Cela peut être dû à Entity Framework utilisant une chaîne de connexion incorrecte. Vérifiez les exceptions internes pour plus de détails et assurez-vous que la chaîne de connexion est correcte.

Détails de l'exception interne:

    System.Data.Entity.Core.ProviderIncompatibleException was unhandled by user code
  HResult=-2146233087
  Message=An error occurred while getting provider information from the database. This can be caused by Entity Framework using an incorrect connection string. Check the inner exceptions for details and ensure that the connection string is correct.

veuillez utiliser la chaîne de connexion correcte fournie dans le didacticiel :

<add name="MovieDBContext" 
   connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=|DataDirectory|\Movies.mdf;Integrated Security=True" 
   providerName="System.Data.SqlClient" 
/>

C'est probablement un problème d'authentification avec l'utilisateur sa.

//Mettre à jour

Je viens d'installer VS 2013 sur ma DevVM (Server 2008R2) J'ai créé un projet Asp.Net MVC 5 et utilisé nuget pour ajouter Entity Framework au projet . Après cela, j'ai créé les modèles et ajouté la chaîne de connexion à le web.config Ensuite, j'ai cliqué sur les commandes -> ajouter -> échafaudage, choisir le contexte et le nom des données du modèle, appuyer sur Ajouter, puis exécuter le projet. Fonctionne comme un charme. Toutes les fonctionnalités de CRUD fonctionnent.

Ma LocalDB a été supprimée. Je le recrée et mon projet fonctionne maintenant avec succès. Merci à tous de me soutenir.

Je crois que cela est causé par 2 chaînes de connexion ... eu le même problème et se débarrasser d'une aide.

ne pas utiliser "." définir le serveur de dbs. utiliser le nom complet de la machine

Veillez à ce que certains fichiers user.config se soient égarés dans le chemin d’être récupérés par votre application.
