Problem with rebuilding the database with code first EF

Hey!

I've created a DB with code first EF and later deleted the DB. Now again I want to create, but when i run project the DB is not created. I think there might be a problem with the settings. What do I need add in settings. here's my code:

public class EFDbContext : DbContext
    {
        public DbSet<Advert> Adverts { get; set; }
        public DbSet<Kind> Kinds { get; set; }
        public DbSet<Age> Ages { get; set; }
        public DbSet<Castration> Castrations { get; set; }
        public DbSet<Coloring> Colorings { get; set; }
        public DbSet<Color> Colors { get; set; }
        public DbSet<Hair> Hair { get; set; }
        public DbSet<Pet> Pets { get; set; }
        public DbSet<Sex> Sexes { get; set; }
        
    }

<connectionStrings>
    <add name="EFDbContext" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=SearchPets;Integrated Security=True"
          providerName="System.Data.SqlClient"/>
  </connectionStrings>

Thanks in advance

P.S. Sorry for my bad english
