我有一个类似于Entity Framework 5.0 PostgreSQL(Npgsql)默认连接工厂的问题

我在app.config中声明了Npgsql:

<connectionStrings>
    <add name="monDbContexte" 
         connectionString="Server=127.0.0.1;Port=5432;Database=ma_datab_db;User Id=postgres;Password=root;" 
     providerName="Npgsql" />
  </connectionStrings>
  <!-- le factory provider -->
  <system.data>
    <DbProviderFactories>
      <add name="Npgsql Data Provider" 
           invariant="Npgsql" 
           support="FF" 
           description=".Net Framework Data Provider for Postgresql Server" 
           type="Npgsql.NpgsqlFactory, Npgsql" />
    </DbProviderFactories>
  </system.data>
</configuration>

我的上下文提供者类:

public class ContextDB: DbContext
{
    public DbSet<Personne> Personnes { get; set; }

    public ContextDB()
        : base("monDbContexte")
    {
    }
}

我的"Personne"课程:

[表( "personnes",模式= "公共")] public类Personne {[密钥] [列( "id_personne")] [显示(名称= "Identifiant")]公众诠释ID为{得到; 组; }

    [Column("nom")]
    [Display(Name = "Nom")]
    [Required(ErrorMessage = "Merci de …

我需要访问User.Identity.Name我的Application_Start()

我将使用它来从我的DbContext获取数据

有可能做这样的事吗？我可以做得更好吗？

    protected void Application_Start()
    {
        AreaRegistration.RegisterAllAreas();

        WebApiConfig.Register(GlobalConfiguration.Configuration);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);

        using (MyApp.ContextDB context = new MyApp.ContextDB())
        {
            var uid = context.SomeDBSet.Where(x => x.WinID == User.Identity.Name).FirstOrDefault();
            Application["uid"] = uid ;
        }
    }
