【转】modelBuilder.Configurations.AddFromAssembly in EF Core

EntityFramework 6.x

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
   base.OnModelCreating(modelBuilder);

   modelBuilder.Configurations.AddFromAssembly(typeof(MyDbContext).Assembly);
}

EF Core <= 2.1

public static class ModelBuilderExtensions
{
    public static void ApplyAllConfigurations(this ModelBuilder modelBuilder)
    {
        var typesToRegister = Assembly.GetExecutingAssembly().GetTypes().Where(t => t.GetInterfaces()
            .Any(gi => gi.IsGenericType && gi.GetGenericTypeDefinition() == typeof(IEntityTypeConfiguration<>))).ToList();

        foreach (var type in typesToRegister)
        {
            dynamic configurationInstance = Activator.CreateInstance(type);
            modelBuilder.ApplyConfiguration(configurationInstance);
        }
    }
}

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
   base.OnModelCreating(modelBuilder);

   modelBuilder.ApplyAllConfigurations();
}

EF Core >= 2.2

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
   base.OnModelCreating(modelBuilder);

   modelBuilder.ApplyConfigurationsFromAssembly(typeof(UserConfiguration).Assembly); // Here UseConfiguration is any IEntityTypeConfiguration
}
