EF6 codefirst slow startup - wpf

Question

I'm in a scenario WPF MVVM EF code first.
All start my application I have to initialize the two databases, but lose 10 seconds each time to do everything. there is a way to speed up?
private void InitDb()
{
var sednaComuniContext = new SednaComuniContext();
sednaComuniContext.Database.Initialize(false);//slowly
if (String.IsNullOrEmpty(Ditta) || Ditta == "BaseDb") return;
var sednaContext = new SednaContext(dbHelper.CreateConnectionString(Ditta));
sednaContext.Database.Initialize(false);//slowly
}
SednaComuniContext:
public class SednaComuniContext : DbContext,IContext
{
public static DatabaseHelper dbHelper;
static string _connection;
public SednaComuniContext()
: base(CreateConnectionString())
{
}
private static string CreateConnectionString()
{
dbHelper = new DatabaseHelper();
return dbHelper.CreateConnectionString("ArchiviComuni");
}
public SednaComuniContext(string connString)
: base(connString)
{
_connection = connString;
if (!Database.Exists())
{
Database.Initialize(true);
}
}
public DbSet<ArticoliFamiglia> ArticoliFamiglia { get; set; }
public DbSet<ArticoliGruppo> ArticoliGruppo { get; set; }
public DbSet<Articoli> Articoli { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
Database.SetInitializer(new MigrateDatabaseToLatestVersion<SednaComuniContext, Configuration>());
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}
SednaContext:
public class SednaContext : DbContext,IContext //IDbContext
{
public static DatabaseHelper dbHelper;
static string _connection;
public SednaContext()
: base(_connection)
{
}
public SednaContext(string connString)
: base(connString)
{
_connection = connString;
}
public DbSet<ArticoliFamiglia> ArticoliFamiglia { get; set; }
public DbSet<ArticoliFamigliaImpostazioni> ArticoliFamigliaImpostazioni { get; set; }
public DbSet<ArticoliGruppo> ArticoliGruppo { get; set; }
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
Database.SetInitializer(new MigrateDatabaseToLatestVersion<SednaContext, Configuration>());
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
}
}
Can an entity migration be used for that?

Answer 1

Since the Entity Framework team has moved to Entity Framework 6 to the EntityFramework.dll the initial load of the database slowed down considerably, some of these problems were fixed but building a model with 2 entities at a console project takes 4-5 seconds for me as well. See this open item describing part of this problem:
http://entityframework.codeplex.com/workitem/2298
The only workaround for this would be a loading screen where you show the users some fancy progress bar and display terms like loading this and that important part of the application.
